I just turned on the lights to my tank for the day and took a double take as I saw about 100 small round objects stuck to the intake tube of my filter. I got a pic, but as soon as I turned the lights on and saw them, so did a few of the fish and they pretty much ate them all in like a minute flat. But what's odd to me is that I haven't added any new fish for probably 2 months and I don't have more than one of any species. I know nothing about fish breeding, but don't fish have to sex to get eggs? lol. I'm not even sure which fish it was.
These are eggs right?
