hi

I own a couple Mac.
They have about 50 youngsters of 15 days old.
Several times daily i give them artemia for food.

What can I give them besides artemia?
They would accept dry food, frozen or someting else?

Thanks

Baby brine shrimp or micro worms are easy to keep live foods that work well for apisto fry. I use a syringe to squirt them right to where the fry are so that they always get a good feed.
After they are 2-3 weeks old I start mixing some powdered flake food together with the live food and feed that to get them used to dried foods. After they are on that for a bit they easily switch to flake.
I still keep feeding some live food most days to my apistos on top of a staple of flake or micro pellet

Thanks Regani for the reply

From the first day after free swimming until now day 16 the fry have been eating BBS a coupel of times daily.
So i'll try to mix some powdered flake foot to the BBS

Someone has an idea whate kind of flakes?

Can I use very fine BBS replacement or someting else?

The fry are now 37 days after free swimming. They grow slowy in my opinion. Or is that normal?
They eat a lot of BBS. And are very dificult to accept some dry food! now they start to eat some little Daphnia and mosquito larvae.

Anyone sugestions to improve growth?

Lower the population density (split among multiple tanks) and/or increase the water changes.
thx Mike,

I don t understand wy water changes are so important in order to improve the growth? (Sorry im a newbee with fish and needs so mutch to learn)
I got the same sugestion on a Dutch forum and since 10 days i change more. 10% every 2 days (ll trey more changes form now on).
My thank is 144l bruto with a lot of plants (moss, floating, stem, crypto and echino). 1year old with a good filtration 500l/h and not so mutch fish, 14 Hyphessobrycon amandae, 10 otocinclus, 14 cory pygmaeus and a koppel Macmasteris with +/-50 fry.

Will that be enough?

Fish in Nature live in the world's largest aquarium. Not only that, the water in streams is continually being changed. In an small body of water like your aquarium, pollutants build up and some of these inhibit growth.

thx for the tip

Since a week I do a daily water exchange of 10 to 15%.
And I see some more growth. But they also begin to eat some more mosquito larvae and daphnea (funny to see how they suck up mosquito larvaes).
Dry food they accept difficult. Just a little freeze-dried tubiflex.

I still think they grow slowly
For comparison, some piqs i see on facebook off A. Borelli and A. cacatuoides.

But still 50 fry with mam and dad in the comunity tank.

Or grow the macmasteri so slow?

Hi all,
They look fine (I can only see the uppermost photo). Are they <"Hydra"> on the glass? If they are it would be worth treating them.

If you feed a lot of live food you are very likely to get them.

Hi Darrel,


'You hit the nail on the head' (don't know if i can use this expression in English). But you are right, the tings on my glass are like the Hydra for the pics of the other threid. And the Hydra shows up at the place where i give the fry there live food. Sometimes the Hydra even takes a Daphnia on hold it.

I go to read more off it tonight, but wen you have sugestions i'm happy to hear it.

So many thanks Darrel!!!!!! for u proper analysis. It's nice that you seen it. I thougt that it were some kind of algae and woud ask it at a planted tank forum. But i thinks its here i gona get some good info of the Hydra.
