Ha! Gotcha, in the same boat here. I have a 36 gallon bowfront planted. I have a 55 gallon and a 29 gallon biocube in the sun room. But I am hesitant to do anything else until we move. I also have a little 10 gallon just for some cherries. I was going to go saltwater in the biocube, but after much research I decided against it for now. LOTSA money to do it right!
I like to go smaller, but have different biotopes in each.
I live in Anderson, so if you need advice about local business or anything, let me know.
