New Cory Trilineatus fry! Need some help please!

Post by ArubaSnuba »

A couple of my three lined cories spawned about over a week ago. I was pretty sure that I didn't get a successful batch until I noticed two small frys swimming around in the the gravel bed of my Eclipse System 12. They look like little tadpoles. At least one of my corys spawned again yesterday as I notice some mating activity in the afternoon and see a new batch of eggs tonight.

I have 6 young adult cory trilineatus in the tank along with a very small albino bristlenose (a little more than 1 1/2 inches total including tail), 1 bamboo shrimp and 1 amano shrimp in the tank.

I know my 12 gallon needs a water change but I am afraid that I would suck the fry out with my python. I have not tested water parameters yet but its been abou 2 weeks since the last water change.

I read the sticky on top about hatching eggs and raising fry but am still a bit unsure what to do. I don't have any fry food on hand. I have an All-glass 5 gallon Mini-bow which I use for a quarantine tank. Should I try to transfer the fry to that tank?

I have Hikari Freezed dried Daphnia, will the fry eat this? The daphnia pretty much floats and does not sink to the bottom though. I do have sinking shrimp pellets but not sure the fry can eat those.

For your dire circumstance try putting the fry in a small plastic container with their tank water and floating it in the tank to maintain the same temperature. If you have a sponge in any of your tank filters try squeezing a small amount of water from the sponge into the container. There should be enough micro-organisms in that to keep the few fry happy until you can hatch baby brine shrimp or borrow a microworm culture to feed. Do small frequent water changes on the container,and adding a couple of small ramshorns snails might help keep any possible overfeeding from harming the fry. I've bred this species before and will advise you that they can produce large broods of eggs

Thanks for the reply. I'm completely new to breeding and didn't intentionally breed the cories. I just let mother nature do her work. I don't have a plastic container right now and have never bred brine shrimp. I do have Hikari freezed dried brine shirmp though, will this do?

Is it best not to move them to my empty 5 gallon quarantine tank? I'm afraid they might be eaten. Are they too small to move at this stage? I would probably have to scoop them out with a cup and they would be very hard to catch with a net.

Use a turkey baster can pick one up from a dollar store and is a total lifesaver from transfering new fry to sucking out uneaten food :D

I have my fry in a breeding net so it still gets circulation and the same water/temps etc from the main tank

You can crush most foods up, but you need it pretty fine for the newly hatched. If you have an airstone in thier pen, that usually helps circulating the food from the surface to the bottom.

You've generally got a good 48hrs from hatching in which to nip out and find some fry food anyway.

Depending on the quantity, you may find those already in the tank will do ok if left there (if no predators).
