I have a fluval chi(5 gal) that had a gas light Betts, cherry shrimp, and endlers. The betta died today and since the filter creates a huge blind spot for the betta to hide I'm weighing my options. The tank has 3mm gravel with a hockey puck sized patch of Java moss in the foreground, and anubis in the rear corners. I'm sold that I want dwarf puffers at some point but was wondering if 1 is still enjoyable or hold off until I can keep a group? If I get a puffer I'll move the endlers to my planted tank and leave the shrimp with the puffer.
