Too many fish?

[NH Fish]

I have a 220 FOWLR tank. 75 gal. skimmer tank, and 125 sump. I have about 300-400 # of live rock, DSB in the tank, More sand in the sump. I also have 2 GSM 4++ skimmers in the skimmer tank. 1 runs all the time, the other runs only during the day.
Problem is, that I cant stop adding fish. Right now I have:
2x PJ cards
1 bangi card
3x clownfish
1- 2.5" clown trigger
1- 3" Piccaso trigger
1 Moorish idol
1 3.5" passer angel
1 rock beauty
1 2.5" asfur angel
1 6" foxface
1 3" powder blue tank
1 4.5" Hippo tang
1 3" yellow tang
1 Long nose hawkfish
1 Starry blenny
2x bicolor dottybacks
1 flame angel
1 3" emperor angel
Just added
1 6" H tusk
1 regal angel
1 majestic angel
1 red stripe angel
Question is. should I add another 100gal or so water volume to the sump? do I need more live rock also?
I do 3 gal per day automatic water change with Genesis reef system.
Anything else I should do? I haven't tested water in a while.
All fish are very happy and healthy.
I don't have any CUC due to the fact the fish eat them.
I also have a 3HP DIGITAL PUMP SO I COULD increase water flow

I would double the size of your display. If all those fish live you are going to be grossly overstocked.

IMO thats a lot of big/messy fish so by adding the extra 100G water volume wouldn't hurt at all just make the system more stable. also defiantly try and up the size of the water changes as i suspect there are significant nitrates… if you can try and reduce the number of fish in the aquarium as this will make the fish more comftable

[NH Fish]

cant go bigger with the display.Can go bigger with water volume downstairs

[Theoj]

or reduce the number of fish in the system….

[Scubaken]

Or set up a separate DT.

Either way, too many fish, not enough swimming space.
Can only lead to upset and misery................... For the fish.

Just cuz u add a seperate 100gals doesn't make it better per se. The problem is not completely the total volume, but the amount of space for the fish I'd worry about.
Fish stress adds to disease, ammonia build up and then death, which continues the cycle.
Sure extra volume will dilute that, but there are still too many fish in there. They will get big, produce more waste until ultimately they have premature death.

As stated by others above, either lessen the load or get a larger DT

yeah seems overstocked, do you have a pic of the tank as it sits? you have some sensitive fish with some monsters eg moorish idol with clown trigger, don't think that will work out in the long run

They all seem to get along good now. Who knows later on. Actually the only one I see chasing anything else is the Moorish Idol.

That list of fish won't work long term, honestly depending on how often you feed you will run into a problem in 6 months to 1 year. A lot of the fish you have get big and with growth only comes more aggression. You have all those fish in a 220g, I have a melanarus wrasse and a foxface in my 220g... You can add as many extra sumps to the system as you would like, unless you put a few fish in each of your sumps you still run into the problem of too many fish and not enough as far a filtration capacity goes. You start adding 100g sumps to your system your skimmer becomes worthless pretty quickly

"Overstocked" doesn't do justice to that stocking level. You need to remove a bunch of fish.

this. Also, some of the fish, such as the clown trigger, once mature will "take care" of your stocking problem on its own.

[Fishmommy]

There are a couple of NH and MA specific reef boards you could unload fish on if you choose.

Most claim one large waterchange weekly, bi weekly etc is far superior to daily water changes. 3 gal of water daily isn't even 2% of the aquarium volume.... Test your water parameters. I would setup your system to do a 20-50 gal weekly or bi weekly change

As stated you will have issues with your fish. Way to many especially since numerous fish get very big and can/will carry a huge attitude. Even the smaller powder blue can become a terror.... My last tank was a 220g and the powder blue was way to small of a tank for his attitude.

Presently I have a 10ft 475g and I made the error of to many fish with attitudes. Sohal tang killed my show queen angel and XL blueface Angel.

I would remove 2+ large Angels as well as the clown trigger.... Possibly more. All those fish can get over a foot long with lots of attitude......
