Since this board has been up, we have found there are several questions that routinely get asked in order to help diagnose problems. If you can have that information to begin with in your post, we'll be able to help right away (if we can!) without having to wait for you to post the info we need.

1) Your water parameters - pH, Ammonia, Nitrite, Nitrates and salinity (if appropriate). This is by far the most important information you can provide! Do not answer this with "Fine" "Perfect" "ok", that tells us nothing. We need hard numbers.

2) Tank size and a list of ALL inhabitants. Include algae eaters, plecos, everything. We need to know what you have and how big the tank is.

3) Feeding, water change schedule and a list of all products you are using or have added to the tank (examples: Cycle, Amquel, salt, etc)

4) What changes you've made in the tank in the last week or so. Sometimes its the little things that make all the difference.

5) How long the aquarium has been set up, and how did you cycle it? If you don't know what cycling is read this: Fishless Cycling Article and familiarize yourself with all the information. Yes. All of it.

We want to help, and providing this information will go a LONG way to getting a diagnosis and hopeful cure that much faster.

While you wait for assistance:
One of the easiest and best ways to help your fish feel better is clean water! If you are already on a regular water change schedule (50% weekly is recommended) a good step to making your fish more comfortable while waiting for diagnosis/suggestions is to do a large water change immediately. Feel free to repeat daily or as often as you can, clean water is always a good thing! Use of Amquel or Prime as a dechlor may help with any ammonia or nitrite issues, and is highly recommended.

Note - if you do not normally do large water changes, doing a sudden, large water change could shock your fish by suddenly changing their established water chemistry. Clean water is still your first goal, so in this case, do several smaller (10%) water changes over the next day or two before starting any large ones.

What killed my puffer?

Post by fortknox82 »

Im reaching out because I don't want anything else in my tank getting sick.

Tank is small 3 gallon. I had 2 dwarf puffers and a coy catfish. Moss ball. One live plant. And everything else is artificial.

The tank had been established for at least a couple months.

I had an ammonia spike and algea bloom one day. So I started doing 50% water changes every day. And I used api ammo lock right at the beginning to knock the levels down.

Everyone in the tank seemed happy but one puffer after this had like road rash on top. I thought him and the other puffer might have been fighting as they do that sometimes.

It didn't get any better but it did get slightly worse. He was eating fine for a while but then I noticed it slowed. Checked tank and all water tests were good. Couldn't find anything online.

And then overnight he died. Im just trying to find out the cause so I can be sure the other fish are fine. See attached pic of damage to his skin:

Fighting or possibly heater burn. I highly suggest moving these guys to a 10g tank. 3g is barely large enough for a single DP.
You are getting sleepy... you only hear the sound of my voice... you must do water changes... water changes... water changes... water changes...
