I have a kole tang in my 125G tank. A friend gave me a powder blue that is currently in QT. I'm hoping these two will get along. If I go by what I've read here, they should, right? Being from two different families? Apparently the kole needs 70 gallons and the powder blue needs 100 gallons, I have a 125 tank. Could this work out or am I pushing it too much? I have a 20G sump that's full of water and I don't have a whole lot of fish in my tank.
I took the powder blue because my friend had a 72G tank and the powder was picking on his blenny really bad. My friend was going to get rid of this fish in some way, so I saved it. It's a beautiful specimin. He had it for a couple years and it's fat and healthy. I know they are hard to acclimate to captivity, so he got lucky. I just couldn't turn it down. I also don't want to get rid of my kole.
