Can i do this?

i have a 30 gallon and i want two or three of yellow spotted anthias. here is a link. Anthias , saltwater fish aquarium - Aquatic Connection just scroll to the very bottom.

 

That 20 gallon would be for one. If you want two or three you would probably need a 75.

 

No way, they get to about 6" in length and need lots of swimming room to maintain their health, I don't know where they got a minimum 20gal tank, but that's not right at all, even for one. Also, being a deep water fish, dimmer lighting is recommended and also b/c a deep water fish, many of the fish have swim bladder issues. Also, keeping this fish in groups will cause aggression in all but the very largest home aquariums. Sorry to be so blunt, but that's IMO is the way it is.

 

Sorry to be bummers they are great looking fish.

 

i know they are! well what could i put in there that wouldnt be aggressive but would move alot and could get a school of?

 

blue reef chromis (do not mistake a regular blue damsel)

green chromis to a lesser extent

 

i was thinking about those blue reef chromis but would they be aggressive?

 

I don't think they are as aggressive as green chromis. Green chromis are way less aggressive than damsels. You could do 3 if you are doing a reef and 5 if FOWLR.

 

yeah i am doing a reef. i am getting tons of coral tommorrow and wednesday so be looking for my reef build!!! and yeah i will probably get them cause i want a school of fish in my tank. i will probably get those and another clownfish so i would have 1 sixline 2 clownfish and 3 or more blue reef chromis. i am getting a skimmer that is for tanks up to 115 gallons on wednesday so bioload shouldnt be a problem!
