Corydora Catfish Eggs?

[KayBray]

I'm sure his has been posted here before so I apologize. Can someone tell me if these are Corydora catfish eggs. Looks similar to my google search.

I recently had a massive pest snail infestation that required me to replace everything inside of my tank, including the filter. Many of our original fish died. Our Apple snail and our two corydora's survived. I'm hypersensitive to little things in the tank now. I have three freshwater plants that I purchased from Petco, but not from inside their tanks, the pre-bagged, farm grown kind. I they have been in there for a month and I know for a fact that these eggs were not there when I put them in.

Should I leave them be?

Thank you!

Look like it to me. I'd put them in a small container and float it in the tank with an airstone with minimal flow. Lots of water changes, a turkey baster would be good for this. Take the water from the big tank to replace what you take out. When they hatch microworms are a good first food. Once they get to about 1/4 inch they should be ok back in your tank if the snail and corries are still the only inhabitants.

Oh wow. Ok thank you! I am not an experienced tank owner. I have been doing weekly water changes mainly because I purchased drift wood that released tannins in the water that made it look brown. I guess the corys are happier now.

When you say a separate container, do you mean a fry tank? This is NOT a big tank. It's only about 13 gallons. It's one of those Aqueon Widescreen setups. It was for my son but then it became a new little hobby for me. We did end up buying some guppies. I'd like to not have to buy a new tank for them but would be neat to see them hatch.

Thanks for your help.

What I do when I find cory eggs is hang one of those small net fry "boxes" in one front corner of the tank. These are a plastic frame around which you fasten the netting, and the top is left open. Hang the net on the tank frame. The netting is very fine so water will flow through but fish cannot, even fry. Inside the net with the eggs you could place some dried leaves as these are an excellent source of infusoria which is the first food for all fry after hatching. Oak, maple and beech leaves work, or you can buy almond leaves in some fish stores.

There are some important benefits to this method over a small separate tank. First, the water quality will be better as you have the entire volume of the main tank circulating, so the fry grow faster (faster than in smaller volumes). Second, the eggs will hatch and the fry grow in the same water the eggs were laid in, so less fussing over that. And when it comes time to release the fry, just tip the net and out they swim, so again no water differences.

For food, I rely primarily on the leaves; dried leaves do produce quite a lot of infusoria. I add a couple shrimp tablets once the eggs hatch (you won't see the fry, I couldn't anyway, they were so tiny). I was amazed at how quickly the fry began nibbling on these.

I googled some photos to show what I mean about the fry net. I happen to have the first type, with the metal strips that bend to fit over the tank frame, but the second type has suction cups.

I was thinking more of a plastic takeaway container, but if you have room for it I think Byrons idea would work better.
