Thoroughly enjoyed feeding time! Definitely keep doing those. I collect bones and one of my favorites is the alligator gar head. Those teeth are vicious!!! How are Dr. Bombay and Belly doing?
for a fully grown. his redtails are little, but they will need a much bigger tank eventually. as long as the tank isnt cramped (which this one kinda is) they should be fine until they are 2 feet+. getting a pool pond is the best option because its not as much work as a normal pond and they get up to i think 5,000 gallons.
they probably grew all those fish together since babies. when the oscars grow up w other tank mates as babies (other than another oscar) then theyre typically pretty chill
