these are the first catfish i have ever owned. there are 3 pimelodus pictus, which i bought at my lfs today. each one is about the same size as my serpae tetras right now
they are very active and skittish and they are already my favorite fish to date
here are some pics
Nice little pictus you have there, they look healthy. Word of warning though, you may find that they "outgrow" the 30g. Though they are small fish they are very active. I had to keep mine in a 30g temporarily and every time it spooked it would frantically swim around and smack into the glass, I won't keep them in anything less than a 55g anymore.
