I'm interested in getting a betta, but I was wondering whether a 2.5 gallon tank would be sufficient for 1 fish? its one of these:
I need something small and low maintanance. I think it came with a filter, but I dont have it anymore. I also remember purchasing a small cheap heater, but I accidentally melted it.
Do you think I should keep this tank and get a new filter/heater for it, or just upgrade to 5 gallon? Also which heater/filter would you recommend for that size (0or 5 gal. tank?)
