My cherry barb were spawning last night. Are these some of the eggs? They're not in a breeding tank but I might separate the eggs from the barbs, if possible. I'm sure there are some in the gravel, of course, but two of these blobs appeared on the cabomba in the area they were spawning. With the naked eye, the 'blobs' appear to have more round sections to them (this is a very poor, zoomed photo from my phone).
