Hi Phillip, I think the published info's vague because this is a widely distributed species, and local forms seem to vary a bit. It's the 'uncommon cichlid" problem, we can get them commercially, but without locations to tell us which geographic form we have. Thomasi's do vary. That being said, size is what I've used. It's an intangible - once you have a pair, it's obvious they were a potential pair all along. I find males bigger with longer extensions on the dorsal. I know that doesn't help much. Mine spawned in soft water only (20-30 ppm). In a 10 gallon of soft water, they spawned every 3 weeks. Back in 140 ppm tapwater, they shut down completely. A slightly different looking thomasi belonging to a friend spawns in tapwater, but has fewer fry. It's a complicated little cichlid that deserves more attention. Oh yeah, I hope others have had a different experience, but of the 30 or so thomasi from 3 different sources I kept before I got breeding pairs, I could never get a spawn from big ones. Once I got them going, it seemed only medium sized adults were productive. Good breeding medium sized females, paired with big males, never spawned. Back with fish their own size, they never stopped. - -Gary
