Electric blue jack dempsey

I havent kept Blue Dempseys in 10 years. So I'm not sure if they've gotten worse since then.
A fish that produces 400 offspring per brood, throws a ton of genetic diversity across the group. This is an evolutionary trait that helps them adapt to a changing environment. Not all offspring are ment to survive.
In aquaria, we keep most of them alive anyway. So, we shouldn't expect every fish in the broad to be prime stock.
Thats why its best to get a group, then keep the best of that group. The larger the group, the higher your chances of getting prime stock.
In my experience, prime Blue Dempseys will gain full size, be tough/aggressive, maintain health and be beautiful. But, this may only be the top 1%, where other species may see those qualities in the top 40%.
So my solution was, starting with as large of a group as possible and/or getting groups from multiple breeders.
Blue Dempseys aren't for the faint of heart. Be prepared to buy a bunch, cull most of them and start over if your first group doesn't pan out.
Something we should remember with all our fish purchases...

I purchased 3 or 4 of these guys a long time ago and I managed to grow all of them past the 3 inch mark. Granted I had to treat for internal parasites at least 3 times, even without adding new stock to their tank.
I ended up selling the ones I wasn’t interested in keeping and the one I did keep ended up growing to 9 inches in two years. I’m positive he would have still been alive if it were not for his freak accident that killed him.

Definitely slow growers that are less genetically fit - usually if they make it past the 3.5 inch mark no issues from there on.
I find many of electric blue jacks have a jaw deformity as well. I have a coupleI raised up and it is very noticeable.

Actually no parasitic attack currently but I want to gain some knowledge about the treatment methods
I use to use a goat dewormer for my treatments. it was 1mil per 10g of watet. not sure you will find videos on it
For parasites i try to always have levamisole (usually from Gary at select aquatic or fritz expel p) and fritz para cleanse )contains metro and prazi). These two treat a wide variety of parasites
I've started using the med trio aquarium co-op recommends for any new fosh I want to add to any of our established tanks. Better safe than sorry. It's a real PIA to treat multiple fish in large tanks. Always quarantine
