Aquarium Advice Apprentice
I've recently set up a 33 (us)gallon tank with a young rainbow shark and a betta with some other fish the problem is that now the rainbow shark is bigger he's become really aggressive towards the betta and has torn his fins, now the betta is always hidding in the plants and i'm worried he might die. The lfs wont take either fish back. My mum has recently cycled a 5 gallon tank as she was going to start a cold water tank, would this be suitable for my betta at room temprature (23c/73f)? as it has no heater but it does has under gravel filtration.
