[Columbian Shark Catfish]

Some of you guys asked for more/tank shots. Here they are!

But PLEASE READ this:

As you saw in my last pictures, the fish were normal. But in these pictures you will notice Breakfast (the bigger catfish) looks as if he is growing another pair of pelvic fins. He still eats, swims, and acts fine; BUT what he does do is chases Dinner (the smaller catfish) around the tank and tries to I guess sniff his stomach(?) almost 24/7 for the week he has them. His "extra" fins last about a week and he gets them every 2-3 months.

My guess is something to do with breeding?

Anyway: On with the pics

But this isn't the first time this has happened. Is Dinner just too young?

And every website description about them says they've never been bred in aquaria.

Maybe he is maturing...?

I hope they do bread, although I have no experience with any breading of fish + there would be no help on the internet.

Liz also has these but they don't have them, MONSTER
