Hi, ive had my betta setup for around 3 months now and just thought it'd be good to hear people opinions on it. Its a 10 gallon, UG Filter, heater tank. I have a Dragon Halfmoon betta and 2 small 3cm bristlenose catfish in it. Just wanted to know whether i had room for anything else? I have live plants and hiding places, and very rarely see the catfishes so tank always seems really empty. Opinions and suggestions appreciated Thanks!
