Deformed Fish Update

[bellabean]

So I decided to pull all the fish and do a good deep gravel clean. I've never actually done one with my fry tank. Well after pulling the fish I was surprised.

I had mentioned the size difference.
Well all the fish that never grew like the others have a bent spine!


Here's some pics ...

they are so incredibly cute :L xx

Yes they are, very tiny though for 3mos I think
One of the bigger ones uas a slightly bent spine as well. The lighter one (2nd to the bottom in the last pic)
I just don't want to breed them.

Is it the sunburst or the red wag molly that had these?

Were they born like that?
I have guppy fry that were born with bent spines as they were premature, but bent spines in fry can by caused by bad diet, water quality, etc...If it is not genetic, and if you feed them variety of food, they may actually straighten up.
My deformed guppy fry have their spines upward and downward only, so it can't be seen from above at all. Yours look rather curved

 

[bellabean]

Water conditions are good.
They eat an assortment of foods. The others I never really paid close attention too. There was 1 that I noticed right away. Plus one that has it's anus sticking out

 

[snazy]

I don't know. They could have been that way. Just double check for any disease as this could be caused by irritants like parasites or similar. Post a pic of the one with the thing sticking out its back as it could be related.

It can be dependent upon the parents. In local fish stores often fish from the same parents are sold. Often you get fish that are already inbred and then magnified by them breeding. This may or may not be the case with the deformities your seeing.

 

[OldMan47]

A common misconception but: Inbreeding does not cause deformities period. Both fish48 and I and many others have each maintained fish completely inbred for many years and have had no such problems in our colonies. Poor husbandry can lead to preserving a deformity in a gene line by reinforcing bad genes that are present and allowing the defective fish to breed. If you remove any deformed fish from your breeding tanks, you will gradually improve the genetics of the remaining breeders.

in the last pic there are big pieces of food on the top. i would crush it up into "powder" sized bites so they can eat it. The big flakes will just pollute the water.

I had a guppy born in my tank with a bent spine and it lived for three years, which was longer than any other fry that mother dropped so maybe its not a bad thing at all!

Yes I know but thank you.
I just quickly dropped some food in to get a pic. I scooped it put. I give them crushed flakes

What you need to do is simple. Place your deformed fish in an environment where they are not likely to ever have fry that survive. Any typical community tank with poor fry cover will do fine for that. There is no need to harm the fish that you already have.
