I have a 20 gal with 3 Zebra Danios, 4 Leopard Danios, 2 Neon Tetras, 2 (small) Plecos, and a Cory Cat. I am looking for an eye-catching focal point fish. Was thinking a Betta. Would he be compatable? Have been checking into it, just not finding a definate yes or no. I realize my tank would be overstocked, but what better reason to start another tank?
