RTCs 2-3 inches are usually 30 around here.
However Ive seen them for 10-15 when around the 10-12 inch mark at mom and pop stores when they need to get rid of them.
also TSN are about 40 here at the 10 inch mark
Man now I can't wait to get into my new place lol I'm thinking I'm going to build an indoor pond rather than get a custom tank. My man's a bit of a carpenter so I'm sure he'll enjoy something to work on after work lol
