i think there very easy to take care of i had them now for 3 years 1 red tail 9'' 2 yellow tail 13-15'' there very slow growing but very worth it ive only had one die cuz my friend was draining the tank and sucked all the water out and he forgot about it and i came in to see all my fish in that tank dead but other than that there very easy just keep them with the same size fish cuz my yellow tail eat a 8'' bass whole and also a walleye
