Unique Reef-Safe Critter Suggestions?

teddscau · 07/12/2018, 08:16 PM

Hey guys, things are going well with my 90g. I'd like some suggestions on fish-safe, coral-safe, and invert-safe critters. I feel I keep reading about the same fish, but I want something unique. To give you an idea of the sort of critters I like (but aren't necessarily compatible with my tank):

Dragonface pipefish
Seahorses
Seadragons
Frogfish
Anglerfish
Eels
Engineer goby
Firefish
Flame fairy wrasse
Banggai cardinalfish
Pajama cardinalfish
Mandarinfish
Sharks
Cephalopods
Pom Pom crabs
Mantis shrimp
Sea bunnies
Sea slugs
Tuxedo urchins
Tunicates

So, do you have any suggestions for unique critters to put in my tank? Again, I don't want anybody munching on each other.

Cucumbers..
Starfish..
Sponges..
Clams..
Scallops..
Sea Apples..

Valentini89 · 07/13/2018, 07:42 PM

I'm a big fan of the Valentini puffers, but any cathigastar puffer is small enough to go in your tank. They are very nice to watch.

OrionN · 07/14/2018, 05:26 AM

Firefish
Flame fairy wrasse
Banggai cardinalfish
Pajama cardinalfish
Mandarinfish
Pom Pom crabs
Sea bunnies
Sea slugs
Tuxedo urchins
Tunicates

Of your list, these are reef safe and will do well in a usual reef tank. The others have problems in a usual reef tank for one reason or other. Also if something is unique then you won't be able to find/get it.

Uncle99 · 07/14/2018, 07:32 AM

Keep in mind while safe, Mandarin fish require tons of Copepods so you need:
A) lots of rock
B) a mature tank greater than 1 year.
C) no other comptetion for Copepods.

I'm curious, why didn't the Engineer Goby make your list?

OrionN · 07/14/2018, 09:45 AM

They get large and dig a lot and undermined the structure of the rockworks.
They are called engineering goby because they rebuild things like rock works.

And hard to keep particularly for newbies.

hkgar · 07/14/2018, 03:29 PM

From your list I would only consider

Engineer goby - destructive to landscaping and could cause falling rock work
Firefish
Flame fairy wrasse
Banggai cardinalfish
Pajama cardinalfish
Mandarinfish Mature tank ONLY
Pom Pom crabs
Tuxedo urchins
Tunicates-I don't know anything about this one.

They are the movers and shakers. I have a Sleeper Banded Goby(Amblygobius phalaena). It is perfectly clean under all my rock work. If my rocks didnt weight 25 to 40 lbs it would prob move them.
If you have a high flow tank, I would skip the Banggai cardinalfish and Pajama cardinalfish. They do not like to swim out in the current if it is fast moving.

Sponges can put out toxin when they die. Becareful not get them out of the water. If they got air in their Chanels part of them may die because the air will stop some of their circulation.
Some star fish are easy to keep other eat other things and impossible to keep. Scallops are filter feeders and will not last in a normal reef tank. Sea Apple will release toxin when they died or stress and can Kill your tank if they stressed die in the tank.

The last engineer goby I had spun its head around 360 degrees, levitated, and then spoke in an incredibly loud an creepily low voice. . . they are the spawn of satan IMHO. . . they move more earth than a California fault line. . .

Well put

bluecoyote79 · 07/15/2018, 01:10 PM

I just got my first tuxedo urchin and really it. If you have enough algae for it to eat, I think they are interesting to watch. Non reefers seem to like them too.

No argument here. I have one that is ~7" right now and he's a digger for sure. I think my little tiger pistol shrimp has him outdone though. He is literally building a tunnel by stacking old shells and rubble from one rock pile to another right now. He's been working on it for a week or two now. It's fascinating.

10-4. In my case, all my rockwork is secure on the tank floor. My base rocks are all quite large. 20+ lbs. Hopefully I'm safe.

Dragonface pipefish
Seahorses
both of these pretty much require a species specific tank due to feeding needs and their very timid nature
Seadragons
requires a temperate water tank
Frogfish
Anglerfish
will eat anything that might come close to fitting in their mouths
Eels
Depending on species, will eat either your fish or your inverts. In addition, they tend to be very messy eaters producing way more waste than most reef tanks can handle
Engineer goby
get large and tunnel everywhere. If your base rocks are on the glass, not on top of the sand, then maybe
Firefish
Flame fairy wrasse
Banggai cardinalfish
Pajama cardinalfish
All of these are nice, but fairly common fish that do well in most systems
Mandarinfish
same feeding problems as pipefish and seahorses
Sharks
most are too big and require large systems. Very messy eaters
Cephalopods
short lived escape artists
Pom Pom crabs
Cool looking, but often stay hidden so can be difficult to enjoy
Mantis shrimp
may eat your fish
Sea bunnies
Sea slugs
both are beautiful in their own way, but can be toxic when the die, especially in smaller systems
Tuxedo urchins
Urchins are the bulldozer of the sea. As long as all rockwork and frags are secure you should be ok.
Tunicates
very fragile shippers, and will often appear on their own in a well established tank. My 120DT has several small colonies, but some of my rocks have been with me for 30 years

So, do you have any suggestions for unique critters to put in my tank? Again, I don't want anybody munching on each other.

IMHO, the most spectacular looking fish I have ever kept are Leopard Wrasses. Get a couple/3 as small juveniles/females and allow one to make the change to male. They are excellent at pest control and are model citizens in your reef. They can be delicate shippers, so proper QT procedures (TTM/prazipro) are very important. They also require at least a couple inches of sand to sleep in so keep that in mind as well.

hth!

flawedexistence · 07/17/2018, 06:11 AM

Fighting Conch.
Porcelain Crab

hkgar · 07/17/2018, 01:03 PM

Always interesting when the OP asks for suggestions (help) then doesn't join the conversation?

jorda9095 · 07/19/2018, 12:04 AM

teddscau · 07/21/2018, 09:08 AM

Hi guys! Sorry for not responding sooner. The leopard wrasse seem really cool. I've never heard of them before. I'll have to buy more sand for my tank. I wanted to have a deep sand bed for my tank, but the guy at the store talked my dad out of it :/

I bought a tuxedo urchin, three lettuce slugs, a sea hare, Balanophyllia, and a Crocea clam. Unfortunately, the sea hare became unresponsive the next day and died during the night. I was really upset. I'll have to get some more sea hares at some point. It was a Dolabella.

The rest of them seem to be doing well, so that's nice. The clam finally latched onto his perch. I have LEDs, so I put him really high in the tank to make sure he gets enough light.

I've actually been looking into fighting conches and porcelain crabs as well. I really love invertebrates, so this tank's going to be filled with them. I'm also hoping to get a pair of acropora crabs as well.

How many fish would you say I could comfortably keep in a 90g? I want to have Banggai cardinalfish, pyjama cardinalfish, firefish, flame fairy wrasse (1 male, 4 females), leopard wrasse... My parents said they NEED to have a pair of Ocellaris clownfish >_>. Dad also wants a small school of blue reef chromis if there's room.

Thanks for the suggestions everyone!

Oh, jorda, is that cuttlefish(?) full grown?

hkgar · 07/21/2018, 02:03 PM

Sorry but tell dad to nix the Blue Chromis. They will kill each other off.
Quatity of fish is dependent on the efficiency of the bio filtering system (rocks and sand).

Like everything else in this hobby, go sllllow when adding fish (the bio filtration has to increase with each additional bio load (fish, inverts) and have a plane on order of introduction based on aggressiveness, Most aggressive last.

Never forget the two rules of reefing:
1. Nothing good happens fast, GO SLOW.
2. Go even slower than that.

Not a rule but VERY strongly suggested, each new fish MUST go through TTM and Quarantine. You do NOT want to introduce Ick to your tank.

OrionN · 07/21/2018, 02:09 PM

Fairy wrasses cannot be keep in group. They will turn male and there will be WWIII. You can keep multiple fairy and/or flasher wrasses but only one per species in your 90 gal tank.
You can keep harem of Leopard Wrasse but not Fairy or Flasher wrasses. Despite of what books and older information said, you will end up with one per species of flasher and fairy wrasses in a tank.

teddscau · 07/21/2018, 05:29 PM

Are you sure Chromis cyaneus (blue chromis) can't be kept in schools? Every site I've been on says they can be kept in schools. Hmm, okay, just checked some forums and apparently those fish are idiots. Thanks for the heads up!

With flame fairy wrasse, I read that it's a good idea to have a male and a harem of females. I guess to be safe I'd keep them in the quarantine tank for several months to make sure none of the females turn into males. If one does, then I guess I'd have to sell him/her. And what's with marine critters changing sex? I wish freshwater could. I have 3 female crystal red shrimp and 40+ males. Like, what the heck. I don't want that many males >_<.

I'm kind of interested in those little cuttlefish...

Oh, and I'm trying to take things slowly, but everyday, several times a day, my parents whine about wanting a pair of clownfish. I swear, if they don't shut up about those stupid clownfish...

OrionN · 07/21/2018, 06:54 PM

Fairy wrasses are relatively new comers to aquariums. Earlier writing on these fishes were wrong. It seen that they all turn males even with the alpha male in the tank. When this happen one will most likely die.
It seem like there are very few exceptions. I do have two Lubbocki in my 320. They seem to be semi OK. I know of three Flame Fairy Wrasse that have been together in a 8’X4’ tank. They came in as three females about 18+ months ago. Now they are 2 males and one submale. Seem to do OK in this huge tank.
In a 90 gal tank I would rec against having more the 1 Flame fairy wrasse.
