I just reintroduced my female red terror to my 150. I removed her because she quit eating. Everytime I put her back in the big tank she gets picked by pretty much all the fish in the tank, but mostly by my texas and a kenyi. She has a very bad attitude and I had to remove from other tank because she would eventually kill the fish in that tank. She is 5"+. I put her in last night and is pretty beat up. The chasing is minimal now but she just lays at the top of tank. Should I pull her out and try again with a divder in the tank? Should I wait it out? I refuse to lose her. I don't understand how she can be so mean in one tank and so docile in an other.
