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.

Yellow spots on puffers back

Post by Megangi » Tue Aug 07, 2018 7:55 pm

Has anyone ever seen a bright yellow spot on the back of a porcupine puffer? I just noticed it today. It looks like it is kind of under his spike to the point where it’s kind of lifted off his body (but not pointed all the way out. More like how they lift off a bit on the stomach when full).

I don’t have our exact parameters because my boyfriend is not home and he has the water testing stuff. But he is in a tank on his own. Probably only an inch and a half. So a baby as far as I know. We have had him for about 4’k this and I have never seen this.

My boyfriend did say he found a parasite the other day? He scooped it out but I don’t know if that caused the bump and how to fix it?? He’s still eating but is acting odd.

Unfortunately I hate to inform you but it sounds like vibro, which is a fast-killing flesh-eating disease. A photo would help though.
You are getting sleepy... you only hear the sound of my voice... you must do water changes... water changes... water changes... water changes...
