I have a young male apisto cauc with 2 females who is has been doing something strange. He's found a spot in the back corner of the tank beside a plant but not hidden. He's been laying on the substrate and just basically chilling. Is this something possibly breeding related? The trio is quite young though, females are about the size of my cardinal tetras at best. I've seen sick apisto's and this is not the same at all. He is not breathing heavy while doing this, eating well, colored well, etc. Parameters and other fish in tank are healthy aswell. Completly healthy appearing, but curious as to what he might be doing here?
