I already have the chinese algae eater. I bought him as an algae eater to only learn later that he was a chinese algae eater. He was first in a community tank (with danios, guppies, and mollies) He was going after the other fish. Neither fish store would take him back. (I could not kill him) So, I went and bought a 10 gallon. (the tank I am up-grading) He hides most of the time now, I only see him out in the middle of the night and when he sees me he quickly goes into hiding. Do you think he will cause a problem in the bigger tank? Thanks
