Currently, we have a male betta and an ADF in a 2.5 gallon tank. I noticed a few days ago, the betta is punking the froggy! I'm going to separate them today, I think I'll leave the betta by himself in his own tank, but what about my ADF? Any suggestions on who would be a good tankmate for him? I'm most likely going to purchase another 2.5 mini-bow starter, which will come with a filter. Thanks in advance for your imput!
