i got 6 rbp's in my 75gallon and theyve ben in there for a couple months now and they have become very skiddish in the past few weeks...anyone know why this would happen or how i can cool them down....they literally jet as fast as they can when i get anywhere near the tank it freaks me out cuz they sometimes hit me heater and the wallls...if somethin dont happensoon i might just sell em and use the 75 as a breeder for jags or some doviis?? what u guys think
