My German Leopard Discus has been thriving in a 220L tank with stable water parameters. The fish are active and colorful, and the tank setup was manageable with regular water changes. I appreciate the clear care instructions provided.
Richard Mackay –
The fish are beautiful and quite active. I kept them in a bare bottom tank which made maintenance easier. I had to monitor temperature closely, but it’s manageable with a heater.
