Ya I’ve been reading about that online. The 2 goldfish are both very active and definetly seem to be enjoying their new extra space. The pleco is attaching to different sides of the tank which is a little different then it’s normal behavior in the other tank. I know that the pleco is more of a nocternal feeder, but in the other tank there was a little castle that he liked to hang out in. What kind of signs should I watch for to see if the pleco isn’t doing well in the tank?

Color is fading and becoming pale. Cloudy eyes and loss of appetite,cloudy water,breathing rapidly
