Cory fry in a tank with bristlenose?

Hi all. I have a couple of questions about c. aeneas fry and when I can move them into the larger tank. I have eight living in a fry keeper but need to go away for three nights so I am wondering how to keep them safe. Right now the fry are 6mm long and are just starting to eat brine shrimp.

option 1: put them in a larger tank which contains two small (6cm and 4cm) bristlenose catfish, 3mm gravel substrate, decent plant cover, sponge filter

option 2: leave them there, have someone give daily feeds of powdered food (JBL Baby 01)

option 3: put the fry into the tank with the two parents, 3mm gravel substrate, plant cover & driftwood, sponge filter

I'm most concerned that buildup of old food will kill them if they stay in the small fry keeper. The person who can feed the fish isn't up to flushing the fry keeper with new water or anything more complicated than adding a little food, microworms or fresh brine shrimp are more than I can ask.

I'm thinking that they would be fairly safe with the BN cats or the parents, but they would possibly not find food in a big tank with 3mm gravel substrate and if they went in I would not see them again unless they survive and prosper.

How big (deep) are the tanks mentioned?

How big is your frycontainer?

I would not place 6 mm fry (that only just digested their youlksack) with grown corydoras, option number 2 is a nogo imo. It's not like the parents hunt them down, but they get vacuum'ed anyway, when the parents are scavenging around.

Tanks are small - one 18x8x8" (bristlenose) and one 14x14x9" (cory parents and tetras). The fry keeper is a floating 6x4x4" container with three mesh sides. Obviously the tetras would be moved to the tank without the fry.

Keep the tetras with the adult corydoras, and move the youngsters to the Ancistrus-tank. At only 20 cm high they should be fine in there imo.

As a precaution, why not move the ancistrus to the adult corydoras aswell? I prefer to keep my cory-fry without any other size and/or species of fish for the first 6-12 weeks.

Ah well, I bought another tank. Funny how this hobby creeps up on you!

Good choice!

I would keep it barebottom or with only a very thin layer of the finest riversand for the first couple of month.

Best of luck
