I have 6 discus fry in, a 29 gallon BB tank, I changed 90% of the water with filtered tap, and 5 are at the top, and one is laying on the bottom, I added some salt and extra aeration, anything I can do?

make that 5 fry now

I wonder if salt is bad for discus. I know it's bad for angels and they are similar. Just a thought, I've never had discus. I would do another water change to start getting the salt out. Hopefully a discus expert will be along soon.

I changed out about 1/2 the water in my 55 gallon angel tank with no problems, it had five 2 month old angel fry in it.

I didn't mean that the water change was a problem. I don't think the salt is good for them though. I was suggesting another water change to get rid of some of the salt.

ifixoldhouses

well I added the salt after they started to die, as a remedy I thought.

Is it just filtered, or did you add the water conditioner, too? Filtered water still has chlorine and chloramine. Perhaps a drastic temp. change between the new and old tank water could also have caused problems.

charcoal filtered-I put some conditioner too, temp same, they lost some slime coat too, I'm thinking TDS shock

I don't know much about Discus except they are really really sensitive to water conditions. IMO changing 90% was too much and they are probly stressed. Like I said I am not a Discus expert just want to help. What are the readings for ammonia, nitrite and nitrate? What is the pH?

Slug

Probably a pH problem, or difference between tank and tap. You should test both and see what they are at.

Hello ifix. I checked your aquarium information and it states that your water temperature is 90 degrees? I know Discus like warmer temperatures but that may be a bit high. Personally I would drop it "slowly" to 86.
Slug what do you think? (Slug is the Discus Man! )

I'm dropping the temp, it was at 90 at an attempt to try and get them on a different food. They are alive this morning, my test kit is over 2 years old, so I don't trust it, I bought it 4 months ago though.

Shame, I hope they get better soon.

A lot of times i've had problems with my fish being sluggish and acting not right after a WC. Turned out to be more chlorine/Chloramines in the water then i thought and the amount of water conditioner i was adding wasn't doing much. Adding extra water conditioner seemed to help. pH shock could be another cause but that would probably mean the tap is softer then the tank.

I'd suggest getting a new test kit. Even if you don't use it on a regular basis, its good to have a base reading on your water in the tank and tap.

Ken, 90 is about at the top of the spectrum. It can work, but i prefer 86-88 range myself.

Remember, the younger a discus is, the more sensitive they are.

Thank you Slug

I'm glad they made it through the night. Hope Slug can help you get it all figured out.

I am so happy that they made it through the night too!
