Egg identification

  • We are currently upgrading MFK. thanks! -neo
Could be a lot of things - what fish are in the tank?
 
In the tank there is penguin tetras neon tetras albino corydoras bristlenose pleco clown pleco 2 male swordtails I think it might be the corydoras because they tend to breed in colder water and we had a temperature drop recently also I moved the eggs into an empty tank it's got a bit of dirt and sand in the tank will that be a problem to them there is more eggs aswell I just haven't got a picture of them

I’m not super good at egg ID, but the logic is there and cories do breed more regularly than tetras to my knowledge. I guess we will have to wait and see!
 
Yeah I can't wait for them to hatch do you have any info on how long it will take
If it’s a Cory it should be 3-6 days I read. That seems to be a common range for a lot of fish.

I can't get a good idea of the size, but bristlenose are really easy to breed and they lay clusters of fairly large eggs, usually orange or yellow. Just like that. Cories scatter tiny eggs all over, not in clusters.

They look like Cory eggs to me. Looks to be the right color/shape, and most cories lay their eggs onto an available flat surface, where they stick; although they often lay eggs as they're swimming, and therefore are often found in scattered lines, not clumps. Ancistrus and most other Loricariid species also spawn after an influx of colder water, but their eggs are typically slightly larger and they do exhibit parental care, plus they tend to lay eggs in some sort of enclosed area- can be anything from clay breeding caves to the space between a HOB filter and the tank walls. They don't look like tetra eggs, but seeing as I've never bred tetras, I can't be sure. When transferring eggs, make sure the tank has stable parameters and some decent flow; or else they won't develop properly, or so I'm told. If they are cories, the newly-hatched cories do need to be situated onto some sort of microfood; I typically use f/t baby brine shrimp. From the picture, I'm not completely sure if they're fertilized; they may not necessarily be viable.
 
That was the only cluster kind of thing there was about 30 scattered all over the glass which I didn't get a pic of
