Top 3 reasons why fry are not growing

Recommended Posts

Why stop at 3, in no particular order...

High flow rates

Growth inhibiting substances

Feeding frequency

Dissolved oxygen levels

Food protein quality

Cool water temperature

Grade each batch of fry according to size as they grow and seperate into different tanks for more uniform growth rates

Do not mix different fry species together in grow out tanks

Is there a reason why you do not mix different fry species in grow out tanks? Sorry if this is a silly question.

Just a guess here [MENTION=13541]jc12[/MENTION] ...but to keep live bearers from interbreeding, so they remain as true as possible.

A reason for keeping batches of fry separate could be to keep track of their growth rate and so the breeder knows exactly how old the fry are.

Sorry initially I didnt even open the link, was more referring to cichlids but same rules apply.

some reasons would be:

Its all about competition for food.

Males grow quicker than females.

(Some males grow quicker than other males)

(Some females grow quicker than other females)

An Electric Blue will grow quicker than a Demasoni

A Molly will grow quicker than a Guppy

Some are top feeders

Some are bottom to mid feeders

Its sooo much easier to move fry on with a single species per tank

Wait until you have to sort out hundreds of fry when the time comes.. arghhhh

You can even make your own size/grading tools to simply place a net full of fry on top and let them slip through slots according to sizes.

Same here I didn't open the link in the first post. Sorry.

I was thinking of moving guppy fry to the discus fry grow out tank so I can free up another tank. I was thinking if I feed heavily and with discus' requirement of multiple big water changes everyday, food would be plenty for all fry and water quality would still be kept pristine. Just a thought anyway... probably I should keep it the way it is now.
