Culling options??

I recently began breeding a few species of fish in my spare time, not for profit just for fun. I give away what I get to an lfs and friends.

Anyway, because I now have a considerable amount of fry, the amount of deformaties has increased overall too.

How do you cull your deformed fry? I've heard of a few methods. What's your opinion on feeding them to a fish?

Thanks in advance 🙂

When able, I always feel best about feeding them off to other fishes. There's no ideal way to end a life. I've used clove oil, ice water, fridge to freezer, and even swung a net against a hard surface. All of them make me feel crappy. I got out of electric blue rams just because of the number of deformities I encountered. If I have fish large enough to swallow them that's my go-to. When I had the LFS I kept a "pet" alligator snapper just for dispatching larger specimens. Culling is a necessary downside of breeding (or even owning) large numbers of fish. I wish it wasn't.

Nothing good happens fast in an ecosystem.

Thanks, feeding them sounds a lot nicer than having to put a few in clove oil or the freezer. what predator could I get that ideally stay in a 30g

The 30 gallon part is difficult. There are some dwarf pike cichlid species that might fit the bill if you are feeding fry on the sub 1" side.

I was surprised to find this out but apparently clove oil is considered more humane than feeding them to larger fish by some breeders who do a lot of culling, I guess the smaller fish don't always die quickly when eaten.

You could keep a paradise fish in 30gal. Males get just over 4", and I can't keep any other fish with my paradise because they go after everything. I've never had fry around that I needed to dispatch via feeding, but that was actually my plan (if my angels spawned, I was going to feed unwanted fry to the paradise fish).

I've swung the net and used a brick (tipped it over on them) to euthanize fish before- they both felt horrible. I prefer to use clove oil now- if you get the dose right, the fish just rolls over and goes unconscious almost instantly.
