Caviar for snail?
First topic message reminder :
Background: this is corydoras eggs and planorbus snails.
Quick question, can you guess what is about to happen?

Re: Caviar for snail?
Yes, use your players at what they are best at. Ramshorn snails are scavengers and you are the water guy. I use them to clean eggs from algae and fungus and I do as much water change daily. That way they take care of keeping eggs clean and I do take care of keeping water clean. Not all snail poop are going with water change, since water is 90-100% clean it does not affect negatively eggs development. So far it has been reproduce indepently on Corydoras CW010 (orange laser) in Washington DC and Edmonton AB, and on Corydoras boesemani and Corydoras carlae still in Edmonton AB, and as mention earlier on some killie eggs (possibly Rivulus hartii) in Montreal Qc.GaryE wrote:...Anyway, I will take some eggs I don't plan to raise and try them in larger containers, so I can deal better with the wastes.....
I got the same feeling and I did mention it in my presentation. Cherry shrimp do not harm eggs, I put some Corydoras CW010 with cherry shrimps and ramshorns and they did hatch well. I saw shrimps going on the eggs but as there was snails too I could not conclude which one was the best for cleaning. Gammarus (scud) will also do the job I tested them on cory CW010 and it was indepently reproduce on Aspidoras albater eggs in Montreal. I do not like much the use of these shrimps as I do daily water change and snail stick better during water change, shrimps tend to go with water into the sink... Which eggs species have you tested with cherry shrimp?l_l_l wrote:You know what?
Cherry Shrimp are also great to have in tanks with eggs, they will clean them and also remove the non fertilized eggs!

Re: Caviar for snail?
Very good discussion here on egg cleaning. I presume that the cleaning of eggs removes the attachment of fungus and the extraction of dead eggs, reducing the amount of source of fungus that can be circulating in the water.
I like the idea of shrimps and gammarus cleaning eggs. I like the idea of snails cleaning eggs.
Francois : do you still need to add methylene blue / malachite green to the water? If not, this may be the best advantage as a non-medicinal way to hatch eggs. So many species are susceptible to these fungicides and it would be a good practice to use fungicidal organisms to control rather than chemicals.

I have tested with tateurndina ocellicauda eggs that were in a tube without the father to fan them. Shrimp were doing a great job and got great numbers of fry making it out of their eggs.francois wrote:Which eggs species have you tested with cherry shrimp?
Re: Caviar for snail?
I never use Methelyne blue or malachite green (or acriflavene) for any eggs, btw.

Re: Caviar for snail?
I've read an article about several breeders linking the use of Methylene blue to swim bladder disorder in some fish.
http://www.practicalfishkeeping.co.uk/content.php?sid=2074
I would never use it because of that.

Re: Caviar for snail?
No that is the point of it, no more use of chemicals. In fact I lost several spawn of Corydoras CW010 because these eggs were sensitive to Methylene blue and to Acriflavin too. That is the original reason why I tryed snail, because I could not get cory eggs to hatch...alexmtl wrote:Francois : do you still need to add methylene blue / malachite green to the water?
We use Methylen blue in lab as dead cell marker. This dye enter the cell passively and get expulse out in an ATP (cell energy) dependent mechanism. If the cell is dead no more energy and it stays blue. It may have additional side effect as it is used to stop bacterial and fungal progression, not sure if it is the same mechanism as for in vitro cell culture.l_l_l wrote:I've read an article about several breeders linking the use of Methylene blue to swim bladder disorder in some fish.

Congratullations for the Tateurndina ocellicauda. When I bred them I used to calculate how many days it was taking before they hatch, and was removing the tube just one or two days before hatching, so dad was taking care of the eggs and I was taking care of fryes. Fryes are very difficult to feed at first so tiny, which was a surpise, so large eggs and so small fryes. I was not very good at my job, I saved only 12 of them.

The young corys whose eggs were cleaned with snails are growing.

Re: Caviar for snail?
I won't use snails to clean my killie eggs, because the amount of work involved in cleaning their enormous waste production is not worth it, given the return. I don't have a problem with eggs dying here, right now.
This experiment has me thinking about snails a little differently though. Today when I found some killie mops full of pond snails, I removed them without swearing or malice. I then had a short ceremony, apologizing to the snail gods for the things I had done in the past, out of ignorance. To make the ceremony complete, I then sacrificed all the captured snails to my Steatocranus.
It's never too late to reform.

Glad they are doing fine.
Re: Caviar for snail?
Ya, a lot... they might be over 100 in a 5 gallons, with air sponge filter, food at will and near 80% water change each two days. They may find their way to a 20 gallons soon or to get their water change daily.

Re: Caviar for snail?
I moved the young into a larger aquarium, they were 195...
Just to share with you, I tested what I believe are pond snails versus ramshorn snail.
I took 18-19 eggs from Corydoras schultzei (called black venezuelanus) and 7-8 eggs of corydoras panda, and mix them with either pond or ramshorn snails.
Results: only 3 hatch with pond snail and near 20 with ramshorn snails. On this picture there are still some to hatch and some already out of their egg shell. White fry are C.schultzei and darker one are C.panda. I noticed that before C.panda eggs darken as they develop and fry hatch almost black.

Re: Caviar for snail?
Well, that didn't work too well. I had put about 30 eggs in there that were all eyeing up so fertile.
The second day, many of them had fungused but I was still able to get about 5 wrigglers. Yesterday, there were only 2 wrigglers left and today none.
Instead, I now have snail eggs.....

Re: Caviar for snail?
Strange that snails left fungus behind...
At least it keeps on going well with cory eggs, bekateen (Stockton CA) on planetcatfish just got success with Corydoras diphyes and today I put some corydoras venezuelanus eggs with snails....

Re: Caviar for snail?
Just got success with 4 Fundulopanchax nigerianus Rayfield eggs. Got the 4 eggs out of the mop, incubate them with small size snails for 2 weeks with daily water change and got 4 wringlers between Monday and today Wednesday.
