Hi, looking for help for my bnp, for a while my elephant nose has been aggressive to my bristle I've tried different hides for her but she won't use them, got some idea's from people on here. But I got up this morning and my bnp has slight swelling too her eye and nips out of her fin. Also my elephant nose hasn't ate which isn't like him. The only other tank i have is a 16gallon would she be too big for this? It houses my betta and snails. Thanks
