Pregnant Fish

[dutto73]

I think i know the reason, but all of my fish (tetras) are grouping in one corner, i have 3-4 pregnant neons, are they waiting to eat the fry. Q2 how many neons could i put in creche

 

[Lillefishy]

Neons don't give birth to live fry, they're egg scatterers.
Have you tested your water, if so what are the readings?
How big is the tank & what other fish are in it?
If it isn't a water problem it could be that the tetras are intimidated by other occupants, especially if they're in a too small school

I had to buy a new tank 96l (same size as last one) so did a large water change, haven't tested water yet, i do have a bristle nose plec but it is still only small... 2 mollies ( also stay to one side) harlequins, rummy noses, glow lights,white tips, and just got.... Rainbows(can't remember first name), i used old media filter to establish new water

Can you give us he numbers of each fish? Also what Rainbows? Many would be unsuitable for a tank that size.

1 plec 2 mollies 1 glow light 3 harlequins 5 white tips 4 rummy noses 10 neons the rainbows are silver with red outline on fins and tail with a blue hue on body( i would upload a pic but dont know how too,i have 3

This is it
Try again

The pic hasn't worked, sorry

You're keeping quite a few of the fish in insufficient numbers, most of them need 6+.
Try uploading the picture to a photo-sharing website such as photobucket and link here, if you can please

They're dwarf neon rainbows, Melanotaenia praecox I'm pretty sure.

Thank you, just got water tested from LFS they said alls ok, only forgot to ask for the readings, durr!!

I haven't totted up numbers but it strikes me as quite a few fish in there as well. Sounds like stress to me, a combination of too many fish overall but not enough of each species.

I always take a LFS "everyfingz foine" with a pinch of salt, you may well have ammonia issues too. I definitely recommend getting your own liquid tests.

Ok thanks for all the replies. i'll let you know how things go
