I usually check out my tank after come home from work, so I did the same thing tonight. To my surprise, I found these white little eggs in my tank. At first I thought those are snail eggs, but when I looked closer, noticed that they are different from the snail eggs that I saw before. They are bigger with white dots in them. I got 7 platies, 1 tetra, 2 danios, 1 pleco, and 5 corys in my tank. I know platies are live bearers. The only one I can think of egg layer would be the cory. I only have one tank (29g). What should I do now? I saw some eggs on the gravel, and many on the mag float.

I used to breed cories.

If you truly want to hatch them,take them out and put them inside a breeder net in the tank. Mine laid eggs on the sides of the glass so I had to carefully get them off with a credit card and my fingers. Once I got them off the glass I just made them hang onto the inside of the breeder net-they are very sticky and are a challenge to get off of your fingers! Once that chore was over,I use methyline blue in the tank. It's an antifungal and will dramatically raise the success of your hatching. It will turn your things blue in the tank,silicone plants and all so remove what you don't want tinted.

I can't remember exactly how long it took for the first ones to hatch,wasn't but four days i think for the first few but it took a whole week for all of the eggs to hatch,it was gradual. Once they were born,I waited a whole day for them to absorb some of their egg sac and for their food,the first week I boiled an egg,Remove the egg yolk,mash it to mustard consistency with some water. Dip a toothpick in the egg mush,and then in the water where the baby cories are. Don't do it more than just a small swirly cloud in the breeder net or you will pollute the whole tank! I did that twice a day,after they got this big _____ and started resembling cories I mashed flake food and bloodworms with a mortar and pestle until it was like fine talcum powder. They thrived on that. I had so many cories I couldn't get rid of them fast enough.

Remove the eggs immediately,the adult cories will eat them as fast as they laid them. Any other questions just ask,I used to love breeding cories it was so easy!

How much of this methylene blue should I use? I only have one 29g tank. The instruction on the bottle said 1 teaspoon per 10gal. I only used half of teaspoon today. I removed the ornaments from the tank, but I still have live plants and driftwood in it.

I followed the directions on the bottle. And I added a few more drops to that. Your water will be a nice deep blue when you've added it according to directions. Don't skimp on it,eggs get fungus on them really fast and you'll be glad you had it.

Live plants and driftwood will be okay. It didn't kill anything in my tanks and I used it all the time.

Forgot to add-remove all the carbon from your filter media when you use the methylene blue!

Are they ALL ate up with fungus? If not,I would. You may have discovered them too late,or they weren't fertilized. It's up to your discretion.

When mine spawned I watched them and made sure the males came up behind the female and fertilized them before I messed with them,and then only a few got fungus. About 90% hatched for me but I was right on top of them spawning. I know you probably can't sit there all day and watch the fish. lol After a few tries you'll get the eye for what's what.

It just happen. I didn't even know corys are egg layers until I saw the eggs. I always have live bearers in the tank. Like guppies, platies.

I think I'm done with the eggs. The eggs probably weren't fertilized by the male cory. They are all cover with fungus. I'm going to do the water change tomorrow.
