woried about the heater

[aquasam]

what temperature is advisable for a 10 gal. with 1.5 week old bronze cory fry .... and baby fish in general?

 

[Allivymar]

Depends on the fish. Bronze corys prefer temps of 25-28C (77-82F); the fry will prefer the same. My angelfish babies are in a tank temp of 85F; each species is different.

Airbreather fry Specially labyrinths often enjoy temps at their high range. Betta fry do best between 82-84 F. but they are able to catch pnemonia in the labyrinth organ.
I think cories only "gulp" air into their gut or swim bladder. So I can't help ya.

Someone here just bred a boatload of cories..bet he can tell you
