Review on Plecoceramics Medium-sized Pleco Cave Breeding Ceramic Decorations for Fish Tanks and Aquariums by Pamela Pickett

I know I have a boy and possibly a girl Albino Bristlenosed Catfish. I've had them for several years now, so they're about 4 inches long. I heard they will mate if I buy a den. So I ordered this cave and put it in the aquarium tonight. When I looked at the span of my shoulder joints and the size of the cavity, I realized they didn't fit me and wanted to have them removed. My husband didn't say too much because other fish might like it. I returned to the aquarium about 20 minutes later and they are either fighting or performing a mating ritual. I really can't tell. But they love it! I just bought another larger model for them before passing the tank. I mean they really love it! They flex their fins and charge forward, head first, tail first, it doesn't matter. It almost looks weird because they are so big. But they got it. Now I'm not sure if one is a boy and the other is a girl because the boy attacked the 'girl' as 'she' swam by. They've never fought and will hang out on glass together all day with no problem. At least if the "girl" is a boy, there will be another cave here in a few days and I will place it on the other side of the tank. I hope I don't have a victim before then.
