Ok so about 2 months ago my sunset platy gave birth to 8 fry. They all seem to be doing well and are still alive. Some however are much larger than the others. I have some that defiantly look like fish and are 3/4 of an inch then I have a few smaller ones, down to a 1/4 of an inch. for one, what do you think is causing this difference? Anyways I had a sick molly and needed to quarantine it so after some water changes and a bunch of moving around I put the molly in the tank the fry were in and I put the small fry in a hatchery in the main tank, and the lager fry I just put in with their mother. They seem to be doing ok. They mostly stay near the bottom or rest behind the filter current and their mother doesn't pay them any attention (they are big enough not to get eaten). Anyways the problem is they don't seem to be eating. I crush up flak food and put it in there but even when they swim by it they dont even look at it let alone eat it. And its not that their mother is eating it all because there is plenty in the tank. They just seem disinterested. Any one have any suggestions?

How long has it been since the move? Sometimes it takes a fish a day or two to settle in and feel ready to eat.

Is it the exact same type of food, brand and everything that you fed them previously? sometimes you have to play tough love to get them to eat new types of food.

Is the tank they are in now the same temperature as the tank they were in previously? Sometimes lower temperatures can make a fish more sluggish and make them less hungry, and the reverse going from cooler to warmer temperatures.

it's not uncommon for fry to grow to different sizes, it's just the way they grow. As far as food goes, how old is it and what type? Nutrafin makes a livebearer food that our platys go nuts for (the guppies too) and I think Omega One also does.
