Polypterus delhezi Day 1~35 from hatching

  • We are currently upgrading MFK. thanks! -neo
Very cool!

So it appears after a week sludge worms aka tubifex worms are a good food. I'm thinking that microworms and or grindal worms could also be ideal? And I'm thinking that a low water level, under 15cm or so would probably also help for the initial stages with the air breathing. Just speculating :)

They eat yolk in day 1~7 and i feed sludge worm after than

Do you keep a lower water level? How often do you do water changes for the fry? What temperature do you like to keep the fry tank at? Also are the sludge worms you feed live or frozen?

I feed them alive and water temperature is 27'c +-1.
For W.C, I do it twice in a week 50% because i don't have many fry now.
When i got many fry, i do 100% w.c for every day or every twice of days

Thank you so much for sharing your knowledge!!!. It means a lot because there are a couple members on here who have gotten their polys to breed, but haven’t been successfully able to raise the fry. So this should help them out a lot!

Thanks for the advice really appreciate it. Do you know if they fry would also accept frozen worms as well as live such as bloodworm or blackworm? Also do you keep any plants or hides in the tank for the fry so they don't cannablise each other?

Generally for fry moving foods are the best, they act on movement :)

I tried almost every food i can feed to them but result is like this

Live altamia: Eat well, can't live long in freshwater
Live sludge worm: Eat well, Can live longer in freshwater than other food -best
Frozen sludge worm: Don't eat well, go bed too fast in aquarium
Frozen blood worm: Too big for fry
Pellet: Too big, eat not so bad, make water too dirty

There are some cannibalism in fry tank but you can make it to minimum with sludge worm free-feeding
