PostSubject: White spot on eggs-normal or not?   Mon Dec 17, 2012 10:43 pm

My common brown BNs have just spawned for the second time. I didn't know about the first spawn until i saw a single baby about 1cm long in my tank! So this is basically like my first time lol. My female has laid her eggs, the male is in the cave fanning them. He has kicked about 40 out so far. I've collected them and put them in a fry net with an airstone beside them, i also have my filter output blowing over them. They are all orange but have a single white spot on them, about the size of a pin head. I've had them in the fry net for 2 days now and the size of the white area has not changed, and the eggs are still orange. Is this normal? Has anyone else experienced this? Thanks!

Hiya,may i ask what sort of cave he is in? If the eggs are orange this is a good sign.You are doing right with the oxygenation.Try to position the air stone beneath the fry saver if possible,as long as it isn't too strong that it blows the eggs all over the place.

P.S The white dot is normal.

Hi Bristlenoses,

He is in a plastic aquarium log which is basically sealed at one end, except for a couple of tiny holes. Yay for the white dot being normal! Thanks for your help! Smile

The reason i asked what cave he had is because you said he kicked some eggs.What has probably happened is that the eggs can't stick properly to the surface of his cave and also the extra holes will not help in some cases.I recommend you getting a different cave for next time.Clay caves are good as they have a rougher surface and no holes in.

Good luck and congrats on the eggs and please let us know what happens.

Ahh! That makes sense! The 'log' is smooth on the inside so that definitely explains why he's kicked out so many fertile eggs! Thanks so much! I will definitely look out for a clay cave replacement. I have also noticed some of the eggs i have in the fry net have started to hatch Very Happy teeny tiny clear/white wriggling tails are popping out. I've been reading up on this site and it's great. So i know the fry will eat the yolk sac for a few days and then become free swimming. Then i will just feed them algae wafers the same as the parents. My tank is 2ft and has only the one male, one female, the single baby from the first spawn, and the new batch. So once theyre free swimming i'll probably just release them into the main tank?

Hi,that is excellent news that they have started to hatch.You will soon be running into problems with too many bristlenoses in a 2 foot tank once they start to grow.They will probably be having another batch almost straight away once the fry leave the cave.Have you got another tank?Yes you can put them into the tank soon.Let them absorb the egg sac and start feeding then pop them in.Then make sure there is always food available in the tank.Cucumber or courgette and a good brand of algae wafers will be a good start.Please let us know how it goes and good luck.
