A year or so ago I picked up 4 upside-down catfish for my 55 gallon. At least that was how the lfs had them marked. Well I soon figured out only 2 were upside-down catfish and the other 2 were what I thought was 'lace' catfish because those were the only other ones that store was selling. Now I am worried these guys are actually feather fins? and I think those will get too large for my 55g?
what do you all think?
