If you mean an L-046 zebra pleco, I would suggest other fish, other than other L-46 zebras or herbivores. L-046 zebras do not compete well for food.
L-046 zebras prefer warmer waters. Good tankmates would be discus. I keep my L-046 zebras in 82°F. I keep RCS (Red Cherry shrimp) and Farlowella catfish with my zebras. I used to keep an L-183 starlight bristlenose, which I later moved into a tank of it's own, which is at around 81°F with cardinal tetras.
