Slow angel fry growth

  • We are currently upgrading MFK. thanks! -neo
Co2 dissolved in water creates carbonic acid which lowers the ph. The ph of the tank is actually very stable at 6.8. I use a small air stone with a flow regulator to keep the co2 in check. Since I use straight tap on this tank, the tds is in the neighborhood of 500. And ferts are liquid, dosed right into the water column.

If the PH isn't changing my main concern would be any direct contact with the ferts as they enter the water column. I can't imagine they would do any damage once diluted but at that concentration, I have no idea. Perhaps premixing the ferts in a couple gallons of water would ease your mind. I'm not sure if feeding BBS exclusively could cause any stunting, I think the fry feed off the parent's slime coat when they are very young.
 
A lot of people who want to push fry growth have them in BB tanks with large and frequent water changes, like 95% every other day. That plus protein rich food and warmer temp (shouldn't be an issue now) would do it. It's no different than what the discus people do with fry. One time I had Geophagus sp orange head Tapajos in a discus tank that I pushed, and they spawned when they were 7 months old.

It could also be the particular strain of angels. Maybe some are slow growers?

I wouldn't worry about it. They will get there. Maybe a few weeks late but so what :)

Thanks for the information. Just wanted to make sure nothing was wrong. Do you think there is a difference between large frequent water changes, and having tons of plants in the tank? Pic of the parents.

The fastest growth I've seen have constant drip filtration systems with optimal temps and high protein diets
 
in my experience you want to raise them alone in a Bare bottom tank keeping the tank pristine and doing a water change every day or at least every other day of about 35% or even 45% and mine have grown like weeds. I feed BBS until they are about 3 weeks old and switch them to crushed flake food and frozen blood worms. I grow them out to almost dime sized in a ten gallon then moved them to this 55 Gal and they blew up!IMG_6260.JPG IMG_6567.JPG
