I recently bought 2 Female Blue Rams for $2.99 each. They are about 1 inch right now. I'm going to buy a male the next time I go there. I also bought 2 Bandit Corydoras for 3.99 each. I put them in a planted 10 gallon and the only agression so far was the Blue Rams locking jaws only happened twice and that was when I first let them in. One of the Blue rams would take a peck at the smaller Corydoras, but then it swims away. They Corydoras just turns around when bit and just scares the rams away, but other than that no damage is done. The 2 corydoras follow each other around and the Rams stay away from each other usually. During the night they swim around the entire tank, including the Cories. They aren't as active during the day. They stay around the plants near the bottom. Right now is the 2nd day I've had them. Rams don't bother the Cories, but sometimes bite each other. Usually happnes when the smaller one gets near the driftwood. Anybody know how to sex Bandit Cories?
