I recently upgraded my splendens Ash into a 2 gal tank with a heater but no filter.
I've been thinking about getting some tank mates for him but there are a few things I would very much like to know so I don't end up with a dead fish.
Is 2 gallons big enough for more than 1 fish?
Do I need a filter for 2 gallons?(I heard that you don't need filter unless its 5 gal but i want to be sure, especially if there are other fish).
What kind of fish are compatible with a not very aggressive betta who is highly active. (He doesn't flare much, only at my other bettas)
in my tank are bamboo roots, a live plant which kind of looks like lettuce (i'm not sure what it is) and decorative pebbles, rocks, marbles and shells.
If anyone could answer these and tell me if it's okay or what I need to change in my tank in order to have tank mates, that would be awesome :D
