Types of Fish in tank

Alright my current stock is a Yellow tang, a Mata Tang, A gold striped maroon clown, 6-line wrasse, and a purple firefish, is my tank pretty much at max? or would i be ok with something else?? and if so, what would get along with these guys? the maroon clown is evil! My tank is 57 gallons any suggestions?

 

You could get another fish for sure, anthias' are cool but really peaceful, my delectus dottyback terrorized my anthias when I first got it. Hawkfish are cool too if you don't have shrimp. Or you could go for a type of dottyback but be aware they can be extremely evil... like mine, just read my signature ha ha

 

rule of thumb is 1 inch of fish per 2 galllons of water so if th fish are 6 inches at adult size ur lloking at 12 gallons but thats my opinion but just take it slow and see what happens

 

Yeah u got room

 

Ummm.... what? 2 tangs in a 57 gallon with a maroon clown? I would say you are at max if not over it. Rules of thumb are terrible ways to stock a tank as they rarely take into consideration swimming space. For instance, a tang really needs a minimum of a 4' long tank and thats even too small for some tangs.

My suggestion would be to leave it as is(unless you are willing to trade in the tangs) for a while and see how it goes. You may run into nitrate issues, aggressiveness issues or even deaths with that fish load.

And now that I have done further research, I would trade in the Mata tang as those get huge and mean fast. They are more suited for a 200+ tank.

Read that. Its a beautiful fish, but gets to 19" long!

Thats is also the reason I hate the inch per gallon rules. That fish need a huge tank, but if you go by th 1:2 inch per gallon you could put it in a 40 gallon tank easily. Problem there is, when full grown, the fish would not be able to turn around. Tangs need a lot of swimming room as they are very active swimmers.

You don't want this:

 

A 6" fish can live in a 12 gallon tank? Are you insane? That rule has no meaning. Space put aside, a 6" fish is going to have an incredibly larger bioload than 6 1" fish.

That tank is overstocked no question. There isn't enough room for tangs who aren't bristletooths and that maroon is going to be very mean when he gets 6" in a tank that size.

 

That tank is overstocked already. I would be taking fish out not adding. Inch per gallon is a dumb rule and doesn't apply at all in sw tanks. 2 tangs alone in that tank is pushing it. I had a yellow tang in my 90g and I felt bad for it cuz it looked like it needed more room.

 

For saltwater I thought the rule was 1" of fish per 4 gallons?

I'd say you are OVERstocked with two tangs.

 

That would put a 6" tang in a 24 gallon with that rule. Not a good idea.
Those rules are absolutely crazy. Each fish has diffrent requirements and should never be put in a tank based on inch per gallon. It actually bothers me that people still use that.
