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.

SAP with Swelling and White Spot

Post by zach210 »

Hi All,

Lurker here for a while -

I recently set up a tank for my South American Puffers and need help identifying what's going on with one of them. It's in constant motion so it's hard to get a great picture but it has a swollen "head" slightly towards its side with a small white protrusion coming out of an indent in the swelling.

This came on pretty quickly as all the fish in the tank were looking great yesterday. However, I did start treating for parasites yesterday with API General Cure (before I read the post a few down on why API GC isn't great). For more context, almost all of them got ich the first week in the tank but recovered quickly after treatment and I assume that most of the came in with parasites as well.

My plan right now is to finish the API General Cure course tomorrow morning and if it's not improving start treatment with Levamisole HCl or potentially a fungal treatment but I haven't been able to diagnose the issue and was hoping the folks here might be able to provide some guidance.

Other than the swelling and white spot it's acting normally and eating well (Mysis and Bug Bites).

Thanks for any insight you all might be able to share.

Could be a cyst. May pop on its own.
They need crunchier foods. 90% of their diet are snails.
