I have a lucky beta in my living room.
He's got a tank all to himself with assortment of house plant cuttings rooting in the gravel. I'm spreading some watersprites in there when the sun angle changes a little more.
I'm thinking of transfering to a 55 gallon with the full air system set for gravel/plant based echo system.
You talk about a spoiled beta. he's gonna have a nice flock of freshwater shrimps and other aquatic creatures when he moves for hunting among the forest of roots and water plants.
