Is A 20L Tank Ok For Growing Out Fry?

As the title states, Is a 20L tank big enough for growing out fry? They are Ice Blue Zebra Fry.

Thanks in advance.

No; fry need at least twice as much water as an adult fish of the same size. I wouldn't use anything less than a 10g for grow out tanks myself and 20g would be better. You can always use a plastic storage box if you don't have/can't get a glass tank.

How many fry do you have?

I have about 10. Where could I get a plastic storage box? HMMM Let me think.

I would disagree with fluttermoth in this regard as I`ve been growing my malawi fry for months now in a 20L arc tank with no problems whatsoever. My fry get to a juvenile size of approx 2.5" and there`s plenty of room for them. You do need to be disciplined with them though and a 50% water change at least every other day and feeding small amounts 3-4 times a day is a must. You`ll see very rapid growth with this kind of schedule

Thank you both for the advice. Does the tank need to have substrate?

No it doesn`t need any substrate, my fry tank is bare bottomed and just has a heater and an air driven sponge filter. It`s much easier to clean out any uneaten bits of food

The whole point in keeping up with the water changes is to give the fry as much clean water as possible, having a substrate defies this logic as it will just help waste to accumulate.
