fish and inbreeding
So i been keeping Balloon Mollies and they keep reproducing. Will inbreeding cause any problems down the road.

In fish interbreeding can always cause issues, most of the time you will not notice it. A prime example is the lifespan of most domesticated guppys. Part of the reason they have such a short life span is duie to the interbreeding to get the large tails and the vibrant colors. On the other hand it is a good way to keep a strain pure. I have a large colony of over 300 endlers that I have just left alone to reproduce amon themselves. From time to time I scoop a couple hundred out and take them to the pet store and they can sell them as pure endlers.

It may cause some deformities, but you can stop this by adding a new fish every few generations.

Fish trading is a great way to keep your lines fresh, find somebody with the same fish as yourself and trade a few after they breed.

Trading is a good way to liven up blood lines. Some people also have good success with line breeding fish and culling any deformities.

once the problems REALLY show up, you'll have more and more born with a curved spine.

The breeders I've met cull fish and try to add new genetics every couple generations.

I would love some endlers but I don't know where to get them and pet smarts are terrible

Hi! I've been researching this subject and I found a great article you might be interested in called Inbreeding is a Good Thing. Although it about another type of fish, perhaps it is relevant to your question.

Chapter 6 and 7 from Fisheries and Aquaculture Department might be good reading too.

I hope this helps.:-)
