I have never had a fish spawn other then guppies and sparkling gouramis so I don't really know what a catfish looks like before it spawns. I am pretty sure I have 1 female and 2 males because the males have always been slender and the one has always been a little thicker then the others. The past few days I noticed she is a lot thicker then normal. Like really fat, is she holding eggs or sick? She is swimming all over the tank, going into the spray bar swimming even near the top of the tank and out in the open. The two males seem to be following her anytime they see her. I am hoping she is carrying eggs and they are trying to spawn with her but don't know for sure.
This first one is all 3 of them for comparison, she is the one on the far left with the 2 males following her, the other 2 are are just her so you can see her swollen stomach.
