Treating Eggs

[Abbeys_Mom]

I am disappointed that of the 20-30 loach eggs I collected, only 2-4 are going to hatch. The rest clouded over and some have fungus. What are people using to prevent egg fungus now, is there anything Non Chemical I can use.

where are you storing the eggs? As I understand it, good waterflow is necessary to help keep fungus at bay.

Also, are you sure the ones that fungused were fertilized to begin with?

I am keeping them in a small acrylic tank. I am not sure if the eggs are fertilized I was collecting them from spawning Dojo Loaches. I collected them yesterday morning, aerated them briefly yesterday afternoon, just to move the water a bit and some are hatching now, approx 18 hours after spawning. Most of the eggs are cloudy, only 2 or 3 are fuzzy.

Water circulation to help keep the eggs from fungusing is crucial to hatching.

Some Methylene Blue in the water, will help prevent fungus on fertilized eggs. But you can only do that if the eggs are in a separate hatching tank. Be careful as Methylene Blue stains badly or wonderfully depending on what you get it on.

few have any experience with loach eggs. if you believe they are fertilized eggs which are getting fungus you could always use an egg tumbler. they run off an airpump and keep the eggs 'tumbling' so they are always getting plenty of oxygenated water at all times. mostly used with mouthbrooders, but I'm sure you'd get a better hatch-rate using one.

Methylene blue works good.

I've used alder cones also and it wasn't bad, but not really great.

Hydrogen peroxide works also, I've dosed it at 1ml/gallon and it seemed to help, although my favorite is methylene blue.

Another thing that I think helps is keeping them in the dark
