My Oscars have laid eggs on a piece of slate twice before. In the first batch, the eggs got fungus, and in the second batch, 2/3 got fungus while a third managed to reach the wriggler stage before they too disappeared (eaten?) The third time around, I transferred the slate to a separate 7-gallon tank with an airstone and added 12 drops of Methylene Blue. After a day, the eggs still got fungus and had to be disposed of!

What shall I do in case they try for the 4th time? They are in a 60-gal long in series with 2 other tanks of catfish, angels and Jaguars, and they have 3 DIY floss+Bio cube filters and a 3-chamber sump, so I may not be able to medicate for fungus in their tank. :help2:
 
The adult fish with healthy immune systems are able to fight off fungus; eggs can't. It seems that your main tank has the fungus and it was brought over on the slate. You need to treat the 60g tank. Change the filter floss and clean the filter media in stages. Then medicate the whole tank. Clean your smaller tank with bleach (cheaper) and have it waiting for the next spawn. Hopefully you will get a batch to survive next time.

Btw, there is a product made specifically to treat eggs for fungus. Next time I am at the LFS I will have a look for you.

Chompers, I spoke too soon! I put off for later cleaning the 7-gal tank and when I lifted the slate, there were about 50 wrigglers under it! Upon closer inspection, among the fungus'd eggs on the slate were also wriggling masses. What shall I do??? I suppose I have to remove the slate at some point. What's next? When will I need to feed the fry? What shall I feed them? Are crushed flakes okay? I really hope you continue your generous advice. Thanks!!!
 
My fry food is powdered flake food. I bought a big can of it and put it all in the blender until it was just almost powder. There are still small bits of flake in it for the growing fish but still a lot of powder. The tiniest of fry can eat it and small fish up to about half an inch can still find it.

I have not had oscar fry yet though, so I am not sure if they require special food (brine shrimp). If the fry are still in the wiggling stage, they will probably not eat. When they become free swimming then they will start to pick at food in the tank.
 
At the very least feed Frozen Baby Brine shrimp. Brine Shrimp promote fast growth. First 1 or 2 weeks, BBS. Thereafter, power/crushed flake food supplemented with live plants to snack on.
 
I use hikari first bites and my fry love them:grinno: 100_2563.JPG

i have never tryed it but if you place the eggs in a new tank don't age the water... the clorine will help to stop the eggs getting fungus and by the time the fish are ready to hatch the clorine should be all gone. a friend uses this method with angels without a problem.

The wrigglers are now swimming, and only a few (10) still have their yolk sacs. I've fed them BBS (Sera Artemia Mix) that a LFS fortunately carries. I'll try to look for Hikari First Bites too, or the Gold pellets (to crush). Can I still keep them in the 7-gallon tank? For how long? What's the best filtration for it? Can someone suggest a WC schedule/percentage of change? Thanks!
