I have a 5 gallon (u.s.) tank for my betta. I know I could put 2 cories in without a problem but could I add an oto or two? I know they like to hang out and I have an algae problem in the tank which I think otos would be the best solution for. Could I just have one oto? The ones I have in my big tank always swim together so I don't know what one of them would do without a buddy. I don't go by the inch per gallon thing either because I do frequent waterchanges and the tank is relatively clean. I am going to get a small heater and sponge filter too.
