Hi All,

Need some help, about 2 weeks ago, my clown loaches had symptons of itch. Around 25th Nov I have raised the temperture to 30C (86F) and threw in some aquariam salt. At the moment, the white spots have nearly gone.

However the problem I have had since, is I had lost a guppy a couple of days later, last week a molly died, and I have just 10 mins ago removed a floating neon tetra.

None of these fish, have shown signs of stress, i.e gasping for breath, red gills etc. All have seemed healthy until the part where they became floaters.

I had done a 25% water change on 29th Nov and another 25% water change yesterday.

Everytime that I have removed a floater, my water parameters have been
0 ammonia, 0 nitrite, 10-20 nitrates. pH about 7-7.2

Raising the temp would this kill the fish like this?

Hello and Welcome

Could you please fill out your aquarium information or simply tell us what the size and what you have in your fish tank this will help us in giving you better advice.

from what i can see the temp rise would have been a bit much for the tetras as they like it below 26 c

however the guppies and mollies should be fine as they can usually tolerate around 29 c so taking it to 30 is not much higher so i wouldnt expect that would of killed them

however you do need to update your info as it states you have onnly had it running for 3 weeks which to me would say it was still cycling, but then you have stated your water perameters which look fine

I'm really sorry for the loss of your fish.

86F is pretty high. The recommended temp for killing ICH is 83/84F
Warm water has less oxegyn and it's advised that aeration is increased during this treatment.
Although, I would think the fish would be grasping for air if this was the cause of the deaths.

Normally when you have less oxygen in the tank you will see the fish at the top of the water gasping trying to pull oxygen from the surface. Warmer water does have less oxygen. Were you running any additional form of aeration while you had your temps so high?

Emory

Thank you for updating your tank information. That really helps us get a better grasp on what you are dealing with.

Are all the fish still holding their own?

Chappells

All I can say is, that the the whole length of the tank (140cm) has aeration bubbles. No fish are gasping for breath or anything. Just last 3 weeks, unexpectandly I have had a floater, every 5 days or so.

Lucy

It's really strange that they're dying with no symptoms.
Have you added anything new to the tank within the last 3 weeks?
Does it correlate with your water changes? Cleaning around the house? Anything like that?

MrsM3197

Sorry Chappells, sounds like you had more than enough aeration in your tank, and your water parimeters are good. Unless the high temp alone stressed them out so bad. Sometimes stuff just happens with our tanks we just can't put a finger on.

I would say (like those before me) that the temp is just a tad high which could stress your fish.

Also - you never said how much salt you added and did you add this as part of a water change or dump it straigh in?

If there was too much salt added too quickly maybe your fish couldn't tolearate this?

try frequent water changes and take your temp down a little and you should hopefully see some im,provements.

(note that water change will only slightly dilute the salts you added so if you add the same each time then the salt will build up...)

Mike19

are you 100% positive about your parameter readings, maybe you should get your water tested at your LFS to check if they are in sync with your results

MrsM3197

Good note on the salt... I wouldn't know for a fact, but I believe that could do it. Too much of anything too quick can have ill effects.

Steve113

Thanks.

I know some people don't use salt at all, I add it very infrequently with my water changes as a tonic but too much could have negative effects.

Care must be taken to make sure the salinity doesn't creep up.

Chappells

I had half the dosage of salt only when I first turnt the temp up. I dissolved it in water first, i.e didnt throw it straight in.

Tank has had two partial water changes since the added salt.

I got the LFS to check the water last week and he said water was fine,

So at this stage one clown loach appears to have a small amount of itch/white spots left.

If I turn temp down will the itch come back again? as its not completely gone, or wait another few days and hope dont die off.

Lastly, rotten things keep moving, I have just counted 8 neon's I should have 9 (lost one had 10), if I have a dead neon that I cannot see, would a decomposing fish kill others?

But I have no ammonia ?

Mike19

Hello,

Like Lucy said 83/84F is a good temp for getting rid of itch if your worried that your current temp of 86 is too high.

in regards to the missing neon situation its possible that if not taken out it can harm your tank although if you cant find it and it appears to be "abducted by aliens as some like to call it" then its possible the other fish just ate it.

Hi Chappells,
What type of salt did you use?

MrsM3197

Chappells, what type of test kit are you using you test your water parameters?

Lucy

The parameters were given in the first post.

I'm stumped

Mike19

This hasn't really been mentioned although do any of the fish seem to be stressed or being stressed by another fish also are you feeding them enough and nothing more then enough.

Chappells

Aquarium Salt, and its liquid test kits. i.e certain number of drops into 1/2 test tube

Mike19

Chappells, anyluck finding a solution, if not its back to the drawing board dw.
