Tail-less babies.
Tail-less babies.
Has anyone seen this happen? Babies are born with tail and over time their siblings/half siblings fight and the tails are gone on 1 fry or 2 fry. Have had this happen in several different set-ups. Fry left with parents and fry removed from parents in their own 10g. Seem to occur when I have different size fry. Any thoughts are welcome?
Just a guess
Hi Ken
I had a fish that was losing a pectoral fin, this was also with fry born over a 3 month period. Ages 2 to 5 months
The tank was bare with a few slate lean too's, 48 inch long, about 35 young.
Anyway as expected all the fry congregated under the lean toos. A lot of squabbling hence I think the loss of the pectoral fin.
I now fill my tanks with a lot of Mopani Wood, still squabbling but a lot more places to retreat to, the pectoral fin is growing back and I have not seen any damage to the other fish since adding the wood.
Hope this helps

Hi Rob and Dave,
Thanks for the response. It is probably due to squabling between them looking for the best hiding, like you say. The ages range anywhere from 1 month to 5 months, give or take. There are around 20 to 30 babies in a 10g. I also have seen this in my breeding tanks where there are only maybe 5 fry in with the adults and parents. All my tanks have many hiding places made from slate, petrified wood, lace rock, and drift wood. My breeder tanks are 20g Long. It is interesting that they like to only congregate in a few locations even when I provide them with many places to take refuge. Of coarse it is always the smallest ones.
I will try getting a photo of the damaged fry.

Hi Ken
I think dave has hit the nail on the head. I was thinking that you were talking about vey young fry.
Squabbling will probably be your answer.
The younger fish do not compete to well against the older. so the gap between the 1 month and 5 month may just be a little too much. Is there any way that you can segregate the tank, i.e perspex with holes drilled in it?

The perfect white lie..."Of course I didn't pay that much for the fish honey"
Hi again
Hi Ken
I found if they had a choice between the wood and under slate, they have a preference for the slate, so in my tanks, slate caves and wood, no other slate decoration these days, the young seem to spread out a lot more.
Good luck

Re: Tail-less babies.
High Nitrats will eat waway their tail. that's the first thing that happens when/if you don't change water often enough, or have a tank that is not established - or if you've cleaned it too wellKenW wrote: Babies are born with tail and over time their
First thing to go is their tails
Thanks for all your replys.
I thinking I will have to spread them out more base on age and add even more hiding choices. I already have a few tanks setup just for the babies and will add a few more. Shouldn't be a nitrate problem it is around 10ppm. The tails of the larger ones are perfect except for maybe 1 or 2 of the small ones.
