Hi folks, I've been trying to condition a bunch of Endlers on Hikari Micro Pellets and Tubifex worms for the past two weeks. The Endlers share a 10G low light planted tank with 6 Otocinclus catfish. Right after my last water change on Friday, I noticed that one of the Otos was very much plumper than the week before. All of them are well fed in general, and I like to make sure that they always have full round bellies, but this Oto was so full that it could only rest on an incline because of the huge belly that got in the way. I haven't had much luck finding otocinclus breeding logs and pictures online beyond mention that the spawning behavior is similar to Corydoras catfish. Most breedings seem to occur by accident with the appearance of fry being the only indicator of breeding. Does anyone have experience breeding them, or have any opinions on the photos I'm attaching? Specifically, is this an overfed oto, a very sick oto or a very pregnant female? Thanks!
