Hi inchworm

I have read loads of times about you using filter squeezings with newly hatched cory fry,i do fancy trying this but wanted to ask a few questions.

Could i put the albino fry in a tank covered in filter squeezings with an airstone without a filter or heater?
Has i'm in the uk,the temp probably would drop below 20 degrees at night...
How long do you leave them in there before the first waterchange and feeding?

Are albinos any harder than some to rear? i've read they can be difficult to get through to adulthood.

Any help would be fab
Thanks

Hi Harlequins

Could i put the albino fry in a tank covered in filter squeezings with an airstone without a filter or heater?

That's the way I do it. I like to use a 2 1/2 gallon tank so that it's easy to do generous water changes.

How long do you leave them in there before the first waterchange and feeding?

At first they will be down in the mulm. From a few days to a week of age they will start doing what looks like hoping around. During this time they will grow considerably by eating the microorganisms in it. Once they start being noticeably bigger and more active, I start adding a bit of microworms or fry food. That's when I start doing water changes and eventually do large enough ones that the mulm gets removed in the process and the tank gets down to bare sand. From then on I start to stir it every few days before water changes to loosen any uneaten food. I change to a box filter once I'm pretty sure they're big enough that they won't get sucked into in.

Are albinos any harder than some to rear? i've read they can be difficult to get through to adulthood.

If they are albino C. aeneus, those and the bronze are ones I would recommend to beginners, so you shouldn't have any problem at all.

Has i'm in the uk,the temp probably would drop below 20 degrees at night...

That's 68 F. and within the normal range for the species. I would think that unless your daytime temperatures go high, it would probably be alright. If in doubt, it won't hurt to have a heater set just high enough to keep from having wild temperature swings in the fry tank. Perhaps Coryologist will see this thread and make a comment. I know he keeps his fish downstairs and his temperatures tend to be cooler than my tanks are.

Good luck with your fry, Harlequins!

Wow thanks inchworm

Lots of good info just what i wanted

Well theres been a slight change of plan,due to the albinos doing mass egg laying this morning,and starting to eat them,i moved the albinos back to the main tank and left the eggs where they are in the fry tank,i think theres on rough count 120 eggs,

She layed them in 3 corners and on the thermometer so i've popped in airstones and added the 50 odd fry from yesterdays hatchings into the fry tank and did rinse a filter sponge in there.
Being pink i can't see them against the sand,so i hope they'll be ok

But i do intend on getting a small 'critter keeper' type tank and will do the filter mulch method on future batches.

I love to have all your tanks and space to breed loads,but has i'm confined to having just one tank available for breeding cories and then removing them to bring on the fry

Depending how these get on i hope to try the other cory species and see if i can breed them all eventually

3 down 4 more to go

Many thanks for your valuable info,much appreciated
