They are 2 feet tank.. with only 8 tetras housed inside..
When I just put them in, they school together, but later one by one apart from each other and start to behave oddly.. they didnt swim properly..
I'm visitting LFS tommorow? what is the important thing that I might want consider to get?
Basically I only have the tank, powerhead + sponge, light and thermometer.
I will get testkit like ammonia, nitrate, clorine, pH, maybe a hydrometer? and what else?
A water treatment... Prime or Amquel+.
