I have not the biological knowledge to offer specifics, but I do know that the higher the temperature for any fish [meaning, the higher within their preferred range] the harder the fish has to work just to live. And this takes a toll on the fish's health. Which is why I always recommend that fish be kept no higher than the middle of their preferred temperature range. One or two degrees may not seem like much to us with our warm blood, but to a fish this can be significant.
Temperature fluctuations do occur in the habitat of all of our aquarium fishes, and the fish are geared for these. The consistent stable conditions in the aquarium is foreign to all fish, which makes higher (or lower at the opposite end) extremes even more of an issue for the fish.
On another note Gwen, if your intention is to spawn the rams, i would not include any catfish or nocturnal fish. The eggs and then the fry are vulnerable at night.
Byron. | Thank you Byron. I'll leave him where he is. I've had my GBR's spawn twice, but each time I don't think the eggs are fertile, and by day 2 they get eaten. I'm hopeful one day it will happen, and that my male is not infertile. Good advice to not introduce any others to what has so far been a successful tank.
Gwen
