The 55 gallon will become an African cichlid tank, probably. The betta tank, well I just wanted a fish tank I'd love, and that's a more natural looking tank. I also think betta's need a good home like any other fish, not a 1 gallon vase that's just one step above the death cups they sell them in at the stores.
In happy news, yesterday when went to clean my tank I found that some of the detritus wouldn't stop moving. Some of the fish in my tank got it on and had babies. Since the fy are dark colored and were hiding in the tree stump that the corys call home I'm guessing that's who they belong to.
