Thanks Willow and Veganchick!! Well currently they are sitting at 74 degrees. They seem pretty happy with it. Plus they love a current,unlike our bettas. I installed a bubble wall recently for them,they have a blast playing in the bubbles hehe.
Also i discovered what those bubbles were. Gas bubbles escaping from the sand. According to aquariumwiki....
It is harmless if it naturally releases itself in small amounts from the gravel and this can be seen as small bubbles appearing from no where from the substrate.
To reduce the levels of this gas, the substrate needs to be kept stirred with a long stick once a week. Or the layer of substrate is kept relatively thin (around 1" thick).
It is heavier than air, so it can accumulate at the water surface if there is not adequate ventilation in the tank hood and so cuts off oxygen from entering the water and so kills the animals that way. Look out for gasping fish.
So have a good filter with a decent flow rate,and an air stone or bubble wall should be fine! I havent seen very many gas bubbles since installing the bubble wall.
