Sorry PC issues! Thanx for all the tips. I'll have to see how I get on. Unsure off strain - where can I find out?

Ah, looks like the parents eating the batch proved to be a prophetic statement :-( Eggs all gone the next day. Still signs look good. My M is @ 6cms and the female about the size of a smallish red tetra (4cm??). The only signs of aggression I've seen from them is the F when the eggs were there and she was busy chasing all others away. I might see about establishing a separate tank for them and see what happens. By egg yolk, you mean the yolk from there eggs and not from a dozen of new worlds finest?

My female cockatoo has just laid some eggs (I think! @ 50 little grey/brown blobs on a rock face with java fern cover and she's mighty protective of the surrounding area and has turned a nice yellow shade). Tank is 90L with 6 glowlights tetras/8 redeye tetras/2 GBA/ and the pair of ciclids. Any help for raising the fry appreciated. Do I need to put them in a seperate tank? Feeding etc? Cheers

No metal holding it down in place. Have put fert balls in place but elsewhere as well so unlikely to be that. Oh well! While I have your attention ... my school of red eye tetras (8) spends its time at the top of the tank hiding behind a plant - no obvious bullying by the male cockatoo ciclid - but not the school of flashing silver bodies I hoped for. Ideas? - they have been in tank for 2 months and where there before the ciclids. Thanks again, you guys have been v helpful.

The substrate is "autumn harvest" as per Animates. Pea sized and is @ 5cms depth with no other material. Whats happening is that in 1 section of tank the gravel is being tinted black - not slimy and doesnt really rub off. Goes thru the entire gravel layer. Also the roots of my Sword plant took on a greyish tinge. Unfortunately at back of tank so cannot really photograph. Cheers.

Tank been set up for @ 6months. Filter churning over at @ 6 times vol/hour. Problem only recent - last fn or so. Will check filters and "de-gunk" if necessary. Any ideas on gravel discoloration? Thanks for prompt replies.

Newbie to hobby with 2 issues: 1. Something that looks like house dust accumulating on the gravel/plants. Greyish/brown colour it doesnt "stick" to things but moves freely when disturbed. Have vacummed but it seems to be everywhere. 2. I had an amazon sword that wasnt growing and the gravel around it was discolouring blackish/grey - the sword also had its roots system turning blackish. Any ideas on what these 2 things are and how to stop? Its a 90L tank - 2x GBA, 2 x cats, 10 x tetras and 2 cockatoos. Water change 25% weekly. TIA.
