Clean-Up Crew for Aggressive Fish Tank
What do people who house aggressive, top-predator fish in planted tanks use for the clean-up crew? Who cleans the hardscape, stirs up the substrate...be the general janitors basically?
I don't have much experience owning animals higher up in the food chain. I have always stuck with peaceful fish. I really really really want to own fish with a bit more personality; but personallity generally equates to aggressiveness which equates to killing the shrimps, snails, etc. whom I rely on for general tank maintenance.
I don't know why people like otocinclus. They are pretty much useless IME. Bigger catfish gets...well BIG...and are more trouble in the long term than the service they provide.
Anyway, I would like to start with some Dario dario, soft-water cichlids, gobies, pygmy sunfish, etc. but would like to know what I can keep with them for clean-up: rasping at plant leaves, hardscape, etc. After years with the basic small schooling fish, mindless drones...I'm getting a bit bored.
