Now I have found Aspidoras fry in the tank. I previously mistook them for Endler fry swimming close to the bottom, but their way of swimming is quite different.

It's a nano tank with no water circulation (except for the weekly change) so I wonder why they would lay eggs at all.

I keep finding these in my nano community tank. There are 3 Aspidoras spilotus, all the other fish are livebearers (Endlers and two small Platies). Could they be Aspidoras eggs? I haven't noticed any catfish fry.
