Yes it should be OK. I would advocate that you use a filter too and do at least a 50% water change weekly.
Forever.
No shark can live in a 3 gallon tank. It would be a nice home for a Betta though!
Any.
you can put a betta in a 54 gallon tank
you can put a betta in a 5 gallon tank
betta fish like at least a 1 gallon tank (nothing smaller) > They can live in a community tank but with no other bettas.
yes! i have a rubberlip,betta and two medium lake snails living a happy life and growing steadily in a ten gallon tank,they are very heathly and happy and the tank isn't over crowded.
actually, betas cant even be in the same tank or else they will start to kill each other. so, no.
A Long life for a Betta is around 30 months.
yes. 3 or 4 neon tetras can live in a 5 gallon tank. they are also fairly cheap.Type your answer here...
no
Personally, I wouldn't keep anything in a 1.5 gallon tank. Not even a single Betta. I consider 5 gallons to be a minimum for a single betta.
