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.

Black spot on F8's belly

Post by Pufferoni »

I have a F8 who gets a black spot on his belly in the area of it's anal vent. It comes and goes but is most prominent after feeding.

It was at least 1 year old when I got him 8 months ago. When I got him he was thin, so I treated him for IPs. I eventually decided that he actually needed his teeth trimmed. He has been steadily gaining weight since.

He appears to be healthy and happy, but I am concerned about the spot.

Any thoughts?

Hmm...mabe the "him" is a "her" and the mark is the fact that she's sexually mature now???

that's my guess....especially since it's in the vent area...

as I said that's a guess.

One of my F8s was the same, the dark area would come and go, always the same spot - same shape, size, etc. Didn't seem to be due to anything in particular and I didn't worry about it too much. I think its just a variation in the coloration.

Clooney has a nice round black spot between his vent and his tail. Or should that be HER vent/tail :yikes:

I do think that it is a possible way to tell the two apart. Like they have to figure it out in the wild right? Many species have *Some* sort of sexual dimorphism, even if it's just a "spot" here or there.....a pheramone leaked into the air/water stuff like that...
