Pray, that the Male knows what to do, Normally they fart around,
and end up eating the eggs, So one day you have a nice clutch of eggs, on
the air tube, glass, piece of slate, or whatever, and the next day you have
nothing.
When they hatch, "not if" be positive, be ready to move them into a net
cage, before they remove themselves from the place they where laid, the
parents will spend all there time collecting any that try and swim of fall
of the bunch, and spit them back on the heap, which is fine, except for
every one they replace 3 more fall off. If you leave them for the parents,
they will starve as they have no idea what food is, but in a small area,
they can,t help but find it. Feed concentrated liquid egg layer formula,
it comes in a tube, or frozen [thaw in hot water] daphnia, Once they get the
idea, your away, and can remove them to another tank.

Hi

Some advice please. I've a large community tanks which has been
established
for well over 2 years (280 lts).

I've 4 angles (6in, 5in & 2x 4 inch all got at same time).

today we notice some unusual behaviour, the larger 2 are driving fish from
one area of the tank are locking jaws & mirroring each others movements.

I'm guessing they are getting ready to spawn. If this is the case any
advice
for a first time Angle dad.

Thanks in-advance
