scale-eater, Malawian
Docimodus johnstoni
Docimodus johnstoni is a Lake Malawi hap with unusual feeding ecology: in the wild it is documented to bite the fins of clariid catfishes and may remove scales/skin, making it fascinating biologically but unsuitable for most community aquaria.
spinycheek sleeper
Eleotris valadei
A neat little sleeper goby from Madagascar and nearby islands, this guy hangs out on the bottom like a bulldog and waits to pounce on bite‑sized prey. It is amphidromous in nature, so adults live in fresh water but the species uses estuaries in its life cycle, and it will absolutely snack on tiny fish or shrimp.
