In the Netherlands you can get it at an apothecary...
Just mix the clove oil with the water, make sure it's well mixed. Add the fish. Narcotic effect starts, fish dies in a few minutes.

Other options are:
- benzocaïne
- 2-phenoxy-ethanol

Both also available at an apothecary.

thanks. I'll try to get some pictures of the second momma and hopefully soon I can get a picture of the first batch of fry

Awesome news about the baby factory, lol

I remember my first yellows fry I actually moved mom to another tank and sold off the fry but then next time
I have some mean fish and they didnt last too long.. of course I wasn't that experienced back then either at creating more holes with rocks, caves, etc.. congrats..
