What To Do With Culls...

OK, so this a topic I don't really like, but here goes--
What do you do with your livebearer culls--either the ones born with defects, or when you just have too many that you don't want to breed?

The story (told 100 times on this site already) is that I got 5 endler livebearer (K class)--2 males, 3 females. 2 of the females arrived mature and already pregnant...and between the 2 of them I now have roughly 100 endlers. I did nothing to try to protect them, but the stories that endler don't eat their fry AND are incredibly hardy are true. I have already separated all the maturing fry by sex, but my first two females keep popping them out like clockwork, and 2-10 gallon aquariums just isn't cutting it. MOST of these aren't going to be the scarlet/chilI type I wanted. They're coming out with everything from snake patterns to a beautiful blue iridescence.

When I got them I sounded the lfs I bought them using my surplus as trade-ins (experience with guppies taught me that there would be more than I wanted, even if I didn't expect dozens per birth and a hundred within the first 3 months...), and they seemed open to it. But this last weekend the manager said that she wasn't interested in endler right now, and that I'd have to establish a relationship and have a constant supply of decent quality, healthy adults, roughly 50 males, 50 females/month IF they wanted them...which they don't. I'm going to talk to the OTHER lfs in my area this week, but I'm not set up to be a breeder at that level, nor do I want to be.

I also belong to the local Aquarium Society, so I am planning on talking to people there, and maybe taking the nicer males and females to the auction next month.

The main problem I have is that I have two endler I know of with defects, who have matured into a male and a female. The male has a herniated abdomen, so insides aren't inside...and has had that since birth. I kept expecting him to get an infection or blockage or something, but no. He's now an adult with his intestines hanging out, and not much I can do. The other is a girl with a bent spine--not as bad as some, but enough that I don't want her to breed. For right now the boy is in with my other boys, the girl is in with the mature females and developing fry. I don't believe the male could breed if he wanted to because of his "fringe". The female on the other hand could, and since she is in the grow-out tank, there is a possibility that I will miss sexing a boy and he will get her before I notice.

Ideally, I will add another two tanks for fry to grow-out in-- a 20 gallon long, and a 27-gallon. But that won't be until the autumn because of time commitments and budget. And that still doesn't really solve my central issue--that unless I find a place for all the unwanted endler to go, I am quickly going to get overwhelmed...again.

So... what strategies do other people who have these incredibly prolific fish use? I have no personal issues with people using them as feeders (since these are hybrids and not of high value to the species)...and am tempted to get a crayfish if there are no better solutions.

Get another tank to keep a predatory fish. Or a group of predatory fish. They'll be well fed on the culls and its takes care of your overpopulation issue.
For guppies and endlers Ive seen people use golden wonder killis (as adults theyre around 4" with large mouths very capable of snapping up guppies. Blue gularis (a %" killifish) is also a voracious feeder as an adult, and makes a beautiful display fish, with a nice secondary function xD Some people get cichlids. I've heard of folks using leaf fish.

I keep a cull container pond and when ppl come over I give them fish from the pond.

I do keep the culls in one big mutt tank. The real disformed ones will be offered to my bulldog goodeids (Alloophorus robustus). The rest kept in the mutt tank and will be sold to an lfs or even be donated to those who are interested.

My LFS will take fish. All you have to do is call ahead and they have plenty of space. They may not take them for credit, but it's what they do.
