obese south american bumble bee catfish?

I got 2 bumble bee catfish as a Christmas present some time last week, both of them were the same size and all of a sudden one of them has a very large belly, I mean this fish looks double the size it originally started.Before then I noticed that it was being very sluggish and staying at the bottom of the tank wile the other fish swam around like crazy. the two fish many times, not a lot would swim and kinda dance together but when one of the fish went to lay next to the other and poke at it , it would just lay down and do nothing. now my bumble bee appears to be fine and healthy except for the fact that it is fat. Could my fish be pregnant? I did some reading and not a lot of people have gotten these fish to successfully breed and others had noticed only one extra fish then they started witch is very strange? Do you think it is possible this fish is pregnant ?

 

A catfish can't be pregnant, because they are egg layers. If it's a female, it's possible it could be egg-bound, particularly if behavior is normal.

Can you get a picture of the fish in question?

 

il try to get a picture but I hardly ever see the lil guy's because they hide all the time, and also I meant egg bound when I said pregnant . oops guess I got the two mixed up.

 

best pic I can get :/

 

Photos are really much easier to view if they're uploaded to fishlore rather than external sites being linked in.

That said, none of those shots provide a clear view of the fish. I would just keep an eye on behavior at this point.
