@Lennie Thanks! I have good luck with anubias. For a long time, the plants in my tanks were primarily anubias and java fern. It had been maybe 15 years since I bothered to try anything else. This past fall, I decided to overhaul my aquascaping and ended up with spare anubias - hence they are now in my quarantine tank! The Q tank also sports a gangbusters colony of phyllanthus and salvinia that I purchased as part of my overhaul. I keep the Q on a seed-starting shelf (I am also a gardener) under seed-starting lights, so the plants are doing pretty well. The plants provide shade so the light isn't so bad for the otos!
Regarding my misspelling, I made a hot mess of the word - I posted with something like "ototincinclus"!
