Woke up this morning and found a whole batch of 2 week old fry all dead in their tank. Temp was good, Water changed daily (aged), feeding 3x/day...hatched bbs. Ive got other angels that are 4 weeks old and they are good. All other fish other than the 2 week old fry are all good. I use the same aged water on all water changes.
I'm trying to figure out what it could be... huh huh
The only difference is I use those pocket hose (the ones that expand) on the fry for 2 days now.
Has anyone have any experience on these hoses? Don't know if it's fish-safe. I assumed it was. Didn't even pay attention prior to using it.
Didn't check my water yet...that's next on my checklist.

..that sucks, Joel..........my $$$'s are on the hose......to be that flexible it has to be made from a different grade of plastic/vinyl...... huh
I used a brand new expandable hose on expensive Discus I had in QT. I was doing 100% daily WC on that tank and I never had any problems. Still, 2 day old fry are more delicate than adult Discus so who knows. Sorry for your disaster.
You'd think if it was the hose it would have done something the first time you used it... unless water sat in the hose for a day after that, soaking up toxins..??
Other than that I can't think of anything.
...figure it out Joel?
My water tested good.
I'm thinking it's the hose. Water sat in it long enough and thinking it accumulated toxic chemicals. And filling up a small 10 gal tank didnt help either. I think the fry are too brittle and didn't tolerate whatever it was that killed them. Maybe the bigger fish are more tolerant to it, that's why Liz's discus didn't get affected.
I did retire that hose. I did read on the insert " Do not Drink water from the hose".
Did a complete clean up on the 10 gal tanks.
I got my last hose at WallyWorld in the camping/Rv section.....it's heavy duty black hose...and 'potable'......in many years I haven't even came close to kinking it.....haven't seen one like there since... huh
When I ran a zebrafish facility, we did a lot of testing of rubber and plastic materials for toxicity and found about 1/3 of them were toxic to baby zebrafish.
Our test was to put some baby fish in a petri plate with the material to test in some water. Controls were the same without the test materials.
Plastisizers that make plastic flexible are usually bad. Many plastic gloves are also.
I'm thinking this is safe for fish....?
