Is it normal for rams just introduced to a tank (properly acclimated) to display a sort of 'nervous' behavior - mainly staying still, occasionally darting, breathing rapidly, etc? I am wondering because I just put a pair of rams into my 10G (they're the only fish there) with water comparable to that at the fish store (temp 79F, ammonia - 0, nitrite - 0, nitrate - 10 ppm, pH 7.0, all tested last evening), after carefully 'acclimating' the fish using the typical 'float the bag for 15-20 mins. and add some tank water to the bag, wait a bit and let them in' technique. I've got a 28W Coralife 50/50 bulb on over them, a big rockscape with caves, and a crapload of java moss and java fern that have been in the tank for several days now. It's filtering through a typical Penguin bio-wheel rated for 20G (set in a corner to reduce water movement). That's all I can think of at the moment. For the 10-15 minutes since I put them in now, they've been displaying the behavior described above. One of the two has calmed a bit more than the other but is still close to motionless. Should I just turn the light off? Any ideas? Something I forgot?
