cories definitely seem to appreciate hiding areas like tunnels, caves etc - this will also give them secure places to lay eggs on

I thought corys lay their eggs on the side of the tank?

Hi LV,

If you look at the pinned topics at the beginning of this forum, you will find three videos that show just what the natural environment of your corydoras looks like. Keep in mind that they are river fish, not lake fish, and are used to having flowing water.

BTW, a few days ago you said you had 10 albinos and 10 bronze corys but today you said you only put 6 of one and 9 of the other in your pond. Why did you not put them all in there?

Ah!... should be interesting to see them in their natural surroundings.... I'll watch it as soon as I get home... my work Internet server has a block to those sites.....

It is called discretion..... (My wife - Cheetah) is under the impression that the show tank in the lounge belongs to her.... so to keep her interrest (in my hobby) alive, I sometimes let her choose some fish to go into the community tank.... (there was only one Bronze in there with the other fish), so she wanted a mate for it and also 4 Albino's - for colour and schooling...... to me, it also affords the opportunity to compare the growth rates of those in the pond, as opposed to those in the tank.....

Between looking at those videos, having some knowledge of breeding aeneus, and knowing how ponds are I've come up with a few ideas. Being fish that like water movement you may want to set up what is known as undergravel jets in your pond. These are usually used in cichlid tanks, this should give you some idea.

Also in those videos you will notice quite a bit of debris, deteriorated leaf litter & mulm on the bottom. I've noticed this looking over various Amazonian videos, and have read that at times the depth can be measured in feet. While it certainly is nothing for a show tank, leaf litter is something I have used in breeding tanks, with that alone as a substrate. Fall is leaf collecting time around here, a good hardwood such as oak or hickory supplies suitable leaves, I load up a bag & store it in the garage.

Knowing that aeneus like to spawn further up on the sides of a tank, while normally staying towards the bottom as seen in those videos, I would provide some natural vertical surfaces, decently stout branches that stick in the bottom & go to the surface should work.

In my mind all of this will provide a spawning area, a deep layer of mulm for the fry to get deeper into and survive on natural micro foods, and water flow. Watching those videos shows the adults skimming the surface, I've noticed with bristlenose fry that they will dig deeper into a layer of mulm on the bottom of the tank, much more than older juvies and adults.

Just some thoughts, I'm no master cory breeder, but it is how I would approach a project such as you mentioned.

From your description here Tolak... it appears that I am on the right track.... I do have a pond (with Goldfish) beneath the trees some distance away from these ponds (where the Cories are kept - amoungst others) and I have to clear out leaves from the G/fish pond regularly, so I'll just transfer these to the Cory pond..... Then also, I have a bag of fine peat, which I got from a pet shop to serve as substrate in a Terrantula cage...., which I will first test in one of the tanks in the fishroom as well as some tree bark chips intended for a reptile cage which I'll also test first.... And finally, I just happen to have one of those filters spare, which I'll place into the pond tonight (which will create a reasonable flow in the pond.....

Then... it is just - Hoping for the best!

 

[Ludwig Venter]

I did put in a stronger (flow) filter this evening.... (after dark), so I went back there now with a torch and it seems like they are frolicking.... even in the dark....

Sounds like your cories are enjoying themselves cories are normally more active at night

The old saying of "as happy as a fish in water" is an understatement for the way these guys are behaving and enjoying their new environment.... They are "schooling" the circumference of their pond constantly with not a second to rest.... They must be covering close on a 100 miles per day. My only concern is that they do not seem to be growing..... (although I can only see them top down).....

Those that I moved to the community tank inside are visibly bigger than they were when I moved them, but the outside lot appears to remain "small".... Is there any "growth" foods I can feed them, or do I just be patient?
