I has a pair of banjo cats that did a disappearing act when they were put in the tank, they buried themselves in the substrate and since they are nocturnal, I didn't get to see them for quite some time. Eventually they would come out when brine shrimp were fed.
that bumblebee catfish that my hubby was refering to resurfaced.. was happily hiding in the 75 gal tank.. until today. Apparently it thought it was faster than the baby peacock bass dudes.. it wasn't. i caught them tearing the poor little darling to shreds just a few minutes ago.. no more little bumblebee catfish.
