Found this 12" female dead this morning. Other rays and fish in the tank are fine. No curl, no wounds, no signs of damage except a pink-ish under belly. Ate last night. She has been in captivity a while and all the other rays have nothing wrong with them. Params are fine, I do water changes every day on this tank.
What happened? Only thing I can think of is a male possibly attacked her ??

Do you age the water, before the water changes, or is it straight from the tap?

Are you Jonathan? Sorry for your loss man.

Thanks everyone!

nice! that sounds good. imma start beleiving that now. hahah makes my life better!.
but anyways ur ray had cancer man. fish cancer can strike at any moment!!!
hahaha
that sucks though. 2 rays in the same week. what bad luck.

haha thanks bro

two rays ? thats sounds more than just bad luck :s

daily water changes ? could it be something in the source water thats affecting weaker rays or something ? are the others eating ok / as normal ?

The other ray never made it into my tank...
It could be my tap water...others are 100% perfect

Sorry for your lost. I believe that when one of your fish died - its' death absorbed one of your bad luck.

That's a much nicer way of looking at it. haha

You may want to check your KH (water hadness). If you have public water, during the winter they may up the chlorine or chloramines because of salt run offs from the roads. They also may do some kind of de-ionizing too, that removes most minerals in the water leaving the pH unstable and liable to crash.

Also, some rays differ from ray to ray on the effects of water params.
And you may want to also increase the O2 in your tank.

This happened to me this past winter, the night after a water change 3X on 3 sepperate tanks. 9yrs of my tap water being fine then lost 3 rays (1-19'' male had for over 7yrs, 1-16'' male had for 5yrs and 6'' female pup cb from my female).

Thanks for the info and sorry about your losses.
I don't think I've ever tested my KH...I'll do that asap..

im sorry

i doubt KH causing a swing in PH is the problem...you said you do daily waterchanges... it would either finds its own happy level or stay the same... i assume you use prime or equal... with out a autopsy of the ray by a scientist who knows these animals its all talking out the azz on what happened... just keep doing what your doing and hope none of the others die...

Freeze and send for necropsy to someone willing to do it. Sorry Rob, I thought you're Jonathan from www.monsterfishrescue.com ...he has a similar ID.

Thanks guys...

Wish I knew a scientist...haha

I've gotten that a few times before.
It's in my freezer still, I'd send it in for a necropsy if I knew someone who could do it...and I don't want to pay a fortune for some guy to dissect my ray.

If they just started treating the water it could very well happen, it happened to me

Sorry to hear this, I lost a castexi ray last year with no signs of anything wrong. I cut her open and posted pics last year. Not sure what caused death.
