As attached. I don't know what these weird circular stuff are but I have two male angels and two ropes in the tank. The items are attached rather firmly to the leaf of an anubias plant.
I am pretty certain that the angels are males as they are very territorial and incessantly fighting. For that matter, one of them is currently injured and is recuperating separately. The eggs came up last night. Ropefish? Anyone could explain more?
I know it would be cool if they were ropefish eggs, but they aren't. Ropefish don't lay them on leaves like that, they swim through dense bunches of aquatic vegetation and release their eggs in there.
You either have two female angels, or a pair. What are you using for a basis of them both being male?
My basis would be that they are completely intolerant of each other, and end up biting or nipping each other. I would think that fish don't have a propogation period for eggs, since the angels had actually been separated on the night in which the eggs had been laid. But I'd admit, I don't know nuts about angels.
An update: the current angel in the tank sits around the eggs constantly, and hopefully they were infertile, because they were probably eaten by either the angel or the ropes over the next night.
