Hi everybody, I am new here to these forums! I have been thinking about setting up a few Betta tanks lately. What would you say the minimum size tank is for one? I was thinking of the Aqueon Evolve 4.
I was also curious as to how many different species of Bettas there are. For instance, is a "Mustard Gas" Betta its own species, or is it just a variant of one species?
Also, would you recommend a heater in Betta tanks? Thanks everybody, I hope to have a great time here!
