View Full Version : Help picking CUC for BB 90 gal

04/26/2017, 06:53 AM
Hello, wasnt sure where to post this, and since this is an invert sub forum, here we are.

I have a 90 gallon flat hex tank, with no sand, plenty of live rock, and a decent supply of "nuisance algae" that ive let build up for a supply of food for a few voracious eaters.

Suggestions on a community of snails and crabs that love left over pellets, and nuisance algae's, that wont have to be flipped over if they fall over, and that dont need sand as part of their normal day/night rotation?

Here is a link to my tank journal

Oh, the lionfish in the tank build is being moved to his own tank this weekend, so he wont be a problem with the CUC

For that size tank I would probably go with 12-15 Trochus snails and maybe 3-5 Scarlet hermit crabs. Maybe a couple Cleaner shrimp as well.

Awesome, thank you!

Do urchins need sand?

I don't think so, but not all Sea Urchins are reef-safe though.

Mk thanks for the input. Going to just do the snails and a few of the hermits for now, I've got a good copepod population going already, so I've been contemplating a Mandarin. No idea if they're the right kind of pod tho.

The urchin I've collected in the Keys have all been coraline eaters, other than a rock boring urchin I had before I knew what it was. I now have a small (the size of a dime) long spine urchin that came with some TBS live rock. It stays on the side and back glass which are covered with coraline algae all the time.

If you are looking for more unusual cleaners, limpet snails and chitons are both slow moving and cleaners.

Those are great ideas, thanks man!
