Im umming and arhing about getting a small fry tank just can't find anywhere to put it

fry produce very little waste so with regular partial water changes, you wont have to worry too much.

 

[RamboFish]

I'm a bit confused about what filter I need

 

[5teady_2012]

You want a sponge filter for fry, that way they dont get sucked in like they would with internal filters.
Best bet is a sand substrate and sponge filter

 

[This Old Spouse]

I've got a HOB filter that I put a sponge over the intake to protect the fry. Works great!

 

[5teady_2012]

As long as it works and the fry are safe thats all that matters

 

[littlenemo]

if the fry produce vwery little waste ammonia then what will feed my bacteria in my filter if there is not alot of ammonia from waste

 

[OldMan47]

The fish themselves don't produce much waste until they start growing but the 3 or 4 feedings a day can more than make up for that. The bacteria will have plenty to work with and water changes for fry tanks are huge and frequent. (Whenever you walk past the tank right to left, feed the fry. When you walk past left to right, do a water change.)

 

[littlenemo]

that often??? how come

 

[This Old Spouse]

They feed just like any other babies ... not very much at one sitting but lots of feedings during the day.

 

[littlenemo]

why so much water changes.

 

[Akasha72]

I keep finding readings of ammonia in my fry tank and I'm changing 50% water either every other day or every 3 days just to keep it at bay. I've no idea why this is happening. If it is true that fry create very little waste (which I believe it is) and my fry food claims to not foul water how can ammonia rise ? It doesn't really make sense to me!

Either way, fry seem to thrive with lots of clean water and lots of feeding. Mine get fed 3 times a day with TetraMin baby and they do very well


Good luck with your fry nemo

Water changes are frequent to minimize the impact of the frequent feedings on water quality. There has also been some speculation that the fry release hormones into the water that inhibit growth as the concentration increases. That may or may not be true but it is well known that very frequent water changes promote far more rapid growth. People who are top amateur breeders do daily water changes of at least 10% on all tanks and some of them go as high as 50% twice a week. These people end up with fish ready to sell at club auctions in less than 3 months that look like young adults.
