I have heard from soooo many people how their ebjds just one day died for no apparent reason! WHy!? I dont want my three ebjds to die! :cry: :cry:

Is it also true that once they hit pass 3 inches, they are safe?
 
I think worrying about it isnt good.

There's not much you can do besides the normal water changes and keeping the water pristine, feeding a varied diet and keeping an eye on them.

With many species, the babies can be very vulnerable under 3".
 
Thats good to hear that they will be strong after 3 inches! Takes forever to even get there though!
 
Water changes are the most important thing you can do. They are really weak fish at a young age compared to a regular jd, so that is probly why youve heard about them dying. just stay on top of your water changes and you should be ok, also it might be too late but when you buy any ebjds watch out for deformities

I agree with above post. Once they are past the three inch mark, they are rock solid!!

Actually, that isn't necessarily true. They are certainly more vulnerable when they are under 3", but I lost a real brute ebjd at about 5.5". Recent conversations suggest that hexmita may be responsible for the mystery deaths. With ebjds, it may be prudent to periodically give them food that has been soaked in medication to deal with parasites, etc. Normally I don't like the idea of prophylatic medicating, but with ebjds it may be a good idea.

I would say that is 100% true. I have never lost a single ebjd that was not under about 2.5". I am speaking from personal experience here I have had a few hundred of these guys over the last couple of years. My two personal babys are at about 6 and 8". They are tough as nails now and live with a large wide bar and some huge green spotted puffers.

If yours died from a protozoa infection. I would not exactly call that a mystery death.

Also I would not treat tank as preventitve on regular basis unless you are constantly adding new fish or live food.

I'm not interested in an extended argument or one over semantics. I didn't say that my fish died of a protozoa infection. It died in exactly the same way that my two other, smaller ebjds died, and exactly like all the others we've been hearing about. I repeated a current opinion that the cause of what people have been calling a "mystery illness" MIGHT be hexameta. So... while you may believe it's 100% that an ebjd over 3" is safe from this kind of death, and though YOUR experience seems to bear that out, in MY experience you appear to be wrong. The ebjd was the only fish in the tank that was affected, and certainly the only one to die. It appeared fine up until maybe a week prior to its death. It was an absolute brute of an ebjd - beefy, thick, looked like it could chew up rocks and spit pebbles. And it died; quickly and for no apparent reason. I believed as you do; that I was home free with this beautiful fish, but I was wrong. It may have been an exception, I can buy that, but to say that it's 100% that an ebjd is ok after reaching 3" is a stretch imo. Your mileage may vary.
 
Hexameta is a flagellated protozoan that is known to infect fish. The infection can lead to death and the symptoms seem to match those of the "mystery" ebjd disease. Whether or not this IS the cause is unknown, but a researcher who has published on hexameta has been approached about participating in examinations of deceased ebjds in the hope that the problem can be identified.
