Here's a weird one. I have a group of young Radixs(Our girl Lucky's kids) 3 of them have formed there on little gang. They won't eat anything but guppies. They turn their noses up at worms. They won't use the same hide as the worm eaters. These 3 stay with each other and avoid their siblings. All 3 are smaller than the other and growing at a much slower pace.
They all have great attitudes when being held and seem to be otherwise normal. These 3 refuse to eat worms or salmon.
At first, I thought it was related to size and that they were intimidated by their bigger siblings. Even when the others are done eating and are full, they refuse to eat anything but guppies. Has anyone else had to deal with something like this. It's not a problems but strange.
