guppy fry problem?

Question

hi i have got 1 guppy fry that is nearly 2 months old and it is tiny it looks a little bigger compare my 2 week old guppy fry that has also survived in the parents tank why is it sooo small

Answer 1

Fish grow according to the size of the tank. So if it's alone in a 5 gallon tank, then it'll grow fast. If it's in a breeder in a 10 gallon tank with lots of fish, then it'll grow very slowly.

Answer 2

It may be due to overcrowding in the tank. You don't mention how large of a setup you've got, but fry need a lot of grow-out space (or frequent water changes if kept in a smaller tank). Rather than a 25% water change once a week, try that amount twice a week. This will also keep the tank cleaner since fry need more frequent feedings, and it will keep the ammonia, nitrite, and nitrate in the tank lower.

Make sure the fry are getting enough light - 12-16 hrs per day - and a good quality food.

Answer 3

many things could be a problem. maybe it is not getting enough food. the food may not be all the nutrition factors it needs but if they all get the same food then i am sure this would not be the problem. could be naturally small or it could be sick. also males won't grow nearly the size of their female counterparts in body girth so if the 2 week old is a female and the 2 month old is a male she could be rapidly catching his girth for that reason. I have around 50 guppies i have breed and even in their mature state the males in particular seem to vary greatly in size, i attribute it to the diff rent types of breeds i have in my tank their all Heinz 57's now as i am trying to make a fish that i like the most. most guppy lovers like pure breeds from a certain type but i try to get diff rent characteristic of each into one fish i am pretty close on a few of them.

Answer 4

It is not unusual to have different sizes, it can be genetic, or it depends on the conditions in the tank (food, water quality).
We are not the same, so fish can be different, too.
I have some "old" guppies, that are smaller than the younger ones.

Answer 5

seize and seperate the fry from the adults. they are going to be eaten. Even a information superhighway breeder field floating will be effective in case you cant have them in a seperate tank. i might want to save my little ones in a 5 gallon bucket, with 2 bubblers and a small heater. I by no potential used filters because little ones might want to eventuallly be sucked into the filter out. i might want to easily weigh down flakes with my hand to very almost a dirt. I unquestionably have continuously saved the water round seventy 5 levels. sturdy success
