I'm seeing mixed opinions on blue/green chromis. Will they be compatible with clowns & cardinals, or not? It seems like the chromis tend to kill each other off after time till you end up with one? Thanks for opinions.
Just to put in my 2 cent's, I have 3 clowns ( 2 false and 1 true) and 6 chromis' and SO FAR they are all ok. The clowns have been in for a long time ( 4 years) and the Chromis' were just added about a month ago. Actually all the clowns and chromis' swim together in a school and its really pretty cool. So for now I'll keep my fingers crossed and hope they all live in peace and harmony. I suppose all fish and all cases are different, but this is my experience so far. HTH
I have 4 chromis in my 125 with a clown fish. I started with 10 chromis and ended up with 4 after about a month. The 4 I have left I have had for quite some time, the only problem I have had is that one of them bullied a pair of anthias I purchased but in time they got along.
They're great little fish singly or in small groups. 1 per 30-40 gallons is what I'd say. If overpopulated, they'll start killing each other off. They ARE damsels, though the best mannered of the ordinary lot.
I HAD two chromis with a clown. The clown would chase both chromis once in a while. Then it got progressively worse. The clown would constantly chase other fish. Woke up one morning and one of the chromis was missing. A few days later, I see the clown take a chunk out of my fairy wrasses tail. I ended up giving the clown to another reefer and I assume the clown killed the one chromis.
Hi & thanks for all the replies. Went to my saltwater lfs and all of their blue green chromis looked pretty beat up so I dropped that idea for now. The bright blue/yellow tail damsels are such a pretty fish - too bad they're not good with other fish (or themselves). I ended up getting a pseudochromis diadema (diadem dottyback) and he's doing great with the others, and swims in & out of tunnels in my LR. Goes in one little hole & pops out of another one. I'm sure he'll soon pick out his little territory & defend it. Pretty fish.
I know that all the pseudo's can be aggressive and territorial. He was chasing my peppermint shrimp around shortly after putting him in the tank, but that has let off now, and I haven't seen any aggression with the clowns or cardinals. He pretty much swims in & out of tunnels in the live rock, and stays mid level in the tank. He's eating too so that's good.
