Something Stuck On My Filter

[DevotedToDiscus]

I had a couple of those eels some years back......they grew massive, and would burrow under the gravel during the day and then pop out at night to feast on my tetras!

looks like hes trying to fertilise the eggs

or s/he could just be fanning them... presumably if they've been laid a while they'll have been fertilised when they were laid, whereas the adults fan them while they develop - that's why if you raise them yourself you have to simulate that by putting an airstone under them to keep the water moving over them...

Anyone know how long it takes for eggs to hatch? Also should i just try and catch them when they hatch and put in a breeding trap?

A few days. I imagine the parents will protect the wrigglers as they are doing the eggs. My preference would be to leave them in the main tank, but divide a portion of it off for them to raise the fry in, then once the fry are bigger you can just remove the divider with the eggs being on the filter housing it'd be difficult to move parents and eggs (or eggs on their own) to another tank, unless you have another identical filter you can swap the media into?
Once they're hatched you could siphon them out into a bucket/another tank using a piece of airline... but I've never seen this done with angel fry, only cory fry.

Thanks for the reply, i feel a bit lost with what to do seeing as they are on the filter.

Yeah, they are predatory. Anything that fits in their mouth is fair game! But they are not aggressive to same size fish.

Usual behavior. My angels have laid eggs about 15 times and eaten them every time after a day or two. When there are other fish about, you don't really have a chance unless you remove the eggs and raise them yourself.

I've had this a number of times. Took me ages to get my first angel brood to last. First was lost to a plec overnight (I actually saw him finishing off the last of the lot, despite the parents tearing at him). Next batch was rapidly just the parents in the tank and they ate them after a few days. Next batch I removed and they died off quickly.

Eventually I had luck with parents in for the first 24 hours or so and then putting a divider in to keep the parents away. When things started to hatch I moved the parents out.

Gutted! I have read online that some people with angels breeding in community tanks were able to keep the eggs by having a dim light on at night (similar to moonlight) so that the angels could still see and better protect the eggs
