Oh no! Sick fish?! Come here and see if someone can help!

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.

Hexamita in puffers?

Post by purplecandle »

I had to look up hexamita earlier today and I began to wonder about something..

Written by Neale Monks,
"Both constipation and Hexamita infections result in the production of large quantities of feces. Constipation doesn't affect how much feces a fish makes, but how easily it can get rid of them. However, because Hexamita infections stimulate the bowel to secrete excessive amounts of mucus, the resulting feces are distinctively pale in color and slimy in appearance."

"Fish infected with Hexamita commonly produce white, stringy feces, and their coloration becomes more subdued than normal. The fish eventually lose their appetite and gradually become emaciated. Often (but not always), lesions appear on the fish’s head. Sometimes, these lesions are also apparent on the fish’s flanks."

This got me to thinking, whenever we see white/pale stringy poo we always recommended treatment for IPs. Unfortunately even with treatment our puffers have a high mortality rate after suspected IPs.

But, is it possible that the white stringy poo we see is hexamita? Perhaps we don't see the holes or lesions on the skin becuase of the puffer's thick skin?

"Hexamitiasis is caused by various species of the protozoan parasite genus Hexamita. These are likely present at low levels in the intestines of many aquarium fish where they do no harm. It is only when the fish is weakened in some way that the parasites can multiply rapidly and spread into the rest of the fish’s body. Once the parasites become established in the other internal organs, the fish soon dies."

Most of us get our puffers when they are half starved or severely stressed, could that be the catalyst?

I guess I am asking, is it possible for Hexamita to be the cause of white stringy poo and then death in our puffers? Maybe because they are puffers hexamita manifests differently than in other fish? Or am I mistaken and IP meds we give our puffers treat Hexamita? Or is it not something a puffer can become sick from??? It is late, maybe I have been thinking about this for too long :shock:

Hexamita has been reported from a very wide range of fish species. It is by no means exclusive to cichlids, though they do seem to show the symptoms more often than many other fish. Metronidazole is the standard medication for Hexamita infections, and can be easily obtained either from pet shops or vets depending on where you live.

Cheers, Neale

I think the Jungle tabs have have metro in them. We bought some metro from a local store to have on hand once we got discus. We feed them good food and haven't had to use it yet and hopefully won't ever.
It is absurd to talk of one animal being higher than another. We consider those, when the cerebral structure/intellectual faculties most developed, as highest. A bee doubtless would when the instincts were.

A number of protozoan infections can cause various IP symptoms. Because of poor treatment in pet stores(one large dose then no retreatments), heximita and other protozoans may be resistant to metronidazole, one of the reasons I like to keep flubendazole around - it occasionally helps with protozoan infections resistant to metro in addition to killing a wide variety of actual worms.
