I only have two tanks. I love my 100Gal community- planted, lots of driftwood and black sand. All my favorite fish..yoyo & clown loaches, Denison barbs, a trio of rams, some otos, a bristlenose & a pictus.
However, at water change time my betta tank becomes my favorite. The betta tank is a 6Gal planted w/ black sand & driftwood, one awesome betta and some otos.
The third tank I will be setting up tomorrow is a Christmas present from me to me! Another 6gal betta tank only this time I'm going with a betta, pygmy cories and white sand, planted.
A 200gal is on the horizon...as soon as the clowns reach 6". Not sure yet on who will be the clowns tankmates. Congo tetras & a large school of ???
