Im thinking of a good bottom dweller for a 20 or 29 gallon community tank with a hi ey gourami, a school of ten neons or cardinals, and 2 amanos. I went to my LFS the other dag and saw Julii corys. But I believe they were false julii since the strip was longer. Im a beginner so how hardy are they? Are they good for a first time cory owner like me?
