My Jaguar Babies Are Dying! Help!

[apex_jaguars]

Hello hobbyist! My 2 year old jaguars "Mickey & Mallory " have breed many times when they we're in my 90 gallon. I always get 700 to 1000 fry every time, but after two weeksa majority of them always die! My Ph is basic 7.5, I do 20 to 30% water changes every other day. I recently upgraded to a 180 gallon tank/ fresh filter media, and the jaguars love it! They laid more eggs than ever, all of them hatched n two days, 1500! I feed them frozen baby brine shrimp, and crushed hikari gold pellets. Everything goes well as usual for two weeks, very strong, then the dying started again! Some do survive, but majority always start wiggling till death, what am I doing wrong! :14:

Welcome to the forum :22:.
How many eould you say are surviving? I don't know about breeding these guys, but I do know you don't want every single one to survive, what would you do with all the fry.

I usually sell them to local pet shops/ I have some 1/2 babies in my 90 gallon tank, 50 survivors outta 700.

50 outa 700 sounds pretty good, in the wild there are many fish species where the mortality rate of fry is higher than that, resulting in maybe 1 in every 1000 making it to adulthood.

Thanks for the welcome!

that makes a lot of sense- I thought in captivity the chances would be higher, but usually after die-offs, the survivors always make it. Thanks for the advice!

Jaguar fry are highly aggressiv as their parents and grow extremely fast when well fed. I have never bothered with brine shrimp since they will accept pellets from day one and grow well on it. After two weeks the fry should be 5-8 mm with some smaller ones and at this size/age they will start figthing among eachother. As well as eating any siblings that fit in their mouth if they are hungry. Make sure that you feed them a looooot. I usually feed 8-10 mashed mid-sized pellets every 2 hours. that will help but you will still have problems with predation etc. the problems get worse as they grow. If you want as many as possible you will need to seperated the fry into smaller groups by size.

The fry should reach an inch before two months of age.

Thanks for the advice ! I feed them twice daily two smashed large pellets + a cube of brine shrimp, they maybe starving! I'm increasing the food, hopefully the dying stops. Thanks!
