One of my RBTAs split so now I have 3. A bit too much for my 50g. So I'd like to trade one for GBTA or other red/orange/green morphs. Any size will work even 1in. I'll be moving all 3 to a new tank soon so they will be detached and you'll be able to pick one that you like. All 3 are in 5-10in size range when opened and very bubbly.
