Feeder fish are like guppies these can be placed in the tank for hatchlings to ambush.
I currently have a 5ft L x 2.5ft W X 20 inches H.
I have to run 2 x 300watt water heats with covers. to reach the desired temp.
One thing i picked up last night at the club meeting was a while back people lost a few from WHITE SPOT no know causes yet or treatment
People debated airration,current,UV,grave,water temps,water treatments and water pumps as some people had sucked them up.
Still alot not know, but we can only feed of other people experiences.
