Hey guys, I have a 29 gallon planted South American tank setup with 12 neon tetras, 5 serpae tetras, 4 oto cats, and soon 2 SA cichlids, but I'd really like to get some sort of cory for this setup as the neons are sometimes too timid to eat and the food drops to the bottom. If I have corys will they eat this food before it can ruin water quality? And would it be alright to get a small school, maybe 3 or 4 with my current stock list?
