Never seen them point like that. The ones I have always had kept their fins out when they sat. The belly almost looks like the bloat you see with mbuna/tropheus. The swelling is in the wrong location and wrong color to be eggs. The fin on the side could be clamping or just awkward sitting.I notice that all Oto's have the same little quirk about pointing to the left.
Thats my 2 cents + being a negative nancy hahaha
