chc / Alex, in the first set of pictures I posted:
3. male - left side
4. male - right side
5. female - left side
Alex, when I do water changes, the new added water is cooler (but not cold) than the tank water. I do large (min 50%) water changes on all my tanks, including tanks with fry.
I think your fish are growing up nicely and already stunning! I think however that they are still a bit too young to spawn. Maybe in another 6 months they will be more interested in each other? But with cichlids, you never know because many will breed at much younger age/smaller size! From reading and research I've done, I think the riverine type you are keeping get much larger, 11+ inches! My largest lacustrine was at least 6 years old and was still only about 9 inches. I think because of this difference in size, the lacustrine is able to breed at smaller sizes.
I don't see any of the "rust" color on my lacustrine compared to the riverine type, however the olive green is more prominent with less spangling. It would be interesting to see if anyone could do more scientific research between these two fish because both types, in my opinion, seem different enough to almost be separate species (shape, coloration, size). Maybe that's a stretch and the differences can really be attributed to environmental conditions?
I got it right from your pictures (fish gender) good on me It's numerous hours watching at my Rostratus paid off!
I also think that my fish is not mature yet, largest male just a lil over 6", others considerably smaller. They less than 2 year old.
Interesting observation: most flaring and tail beatings occurs after the tank lights is off. That’s only the time when I see them pay attention to each other, other then chasing. They do some body shaking, digging sand, but that’s about it for now.
