I have to baby res on is mayne 1 1/2 " and the other is like 2". I have them both in the same tank. One i had for about a month and she eats fine. The other one i got yesterday and is very active and looks at the food and smells it but did not eat it which i am not worried about the new one maybe just getting used to the new home or doe snot know that it is food yet. My question is i do not want to have to feed in a sperate tank. So will the new one when he figures it out just start eating it as soon as it hits the water or will the bigger one always bully him out of the way. Like i said i do not want a sperate feeding tank so what is the best way to go about this.
