A couple of weeks ago I purchased a pair of electric blue ram. They are only young so I'm unable to sex them yet. From the moment they entered the tank, one was always more confident and brave but they did tend to stick together most of the time. Recently I've noticed that the more confident one doesn't seem to want the other one any where near it. If it gets too close it chases it away. There is no nipping, simply just chases it away then goes back to what it was doing. Is this normal behaviour? Could it become a problem? Is there anything I could do to stop it? One other thing while I'm here, I've fed them many different foods, from live bloodworm, brine shrimp to various frozen foods and flakes and pellets. While they instantly eat the flakes and pellets, they tend to chew the frozen food for a few seconds then spit it out, befor chewing it for a few more seconds, then spitting it out again. They sometimes eventually get round to ingesting it but more often than not one of their tank mates will nick the food when the ram has spat it out. Is this something I should worry about? am I doing something wrong?
