I have a 5.5 gallon tank with one betta. I used to have a pleco in there but moved him into a bigger tank when he got older. My betta is alone and is much less active now that he's by himself. Would it be cruel to get a frog or two in such a small tank? Any other suggestions for small tank mates? Nothing too colorful or the betta will pick a fight :/
