Please help with Jack Dempsey breeding question. I have wigglers

  • We are currently upgrading MFK. thanks! -neo
JD spawn like rabbits, once they start you will have fry up the ying yang, JD are usually good parents, I would leave them be, 100 is not very many but good for a first spawn. do you have prefilter socks on your intakes? if not those little guys get sucked up when they rise like a cloud. for food crush reguler fish food, I find a coffee grinder great for this as I can grind up a months feeding in one shot. again having a prefilter sock works great to keep from fowling your filter and the fry will feed off the sock or sponge.
 
raised JD fry for a couple years. when all said and done you only want small school for the grow out then be culling from there down to a good 10 or so.
 
you will also notice once they become free swimmers mom and dad appear to be eating them, this is not so, they are hurdling cats and will spit them back out at the pit they want them to stay in, also, when wiggerlers, after moving to the pit they will spit gravel on them. to some extent burring them, again this is natural, leave em be, they be fine, when they become free swimmer mom and or dad will yank em out and set them to free swimming.

Air pump driven sponge filters are great, they won't suck up any fry unless they are dead. I keep 1 in the parent tank so it is cycled and can move it to a 10 gal. tank for the fry. The smaller tank makes it easier for the fry to find food. If breeding ebjd you want to save every one possible, you don't get many perfect ones due to birth defects. Use water from parent tank and no gravel in fry tank. Lots of luck!
