Parasites on three spot Gourami.
I've been reading and learning a lot from your website, thank
you so much for helping us and our fishes.
I really need your help in identifying the parasites my fish
might have. I have 4-4.5 year old three spot Gourami that has
been healthy and hardy fish for all these years until recently. I
made some bad choices and introduced a fish to his tank that he
was extremely afraid off. He will not come to surface to eat and
got very stressed.
I set up a new 20 gallon tank just for him and transferred the
fish in it once it cycled (water quality is good with 0 for
ammonia and nitrites and under 10 for nitrates), ph 7.5 hard
water with moderate alkalinity.
After the transfer the fish showed signs of irritation, scratched
himself over objects in the tank and soon after develop
small raised white-grayish spots very similar to
Ick but not Ick. I tried to raise the temperature to 88F and
adding salt to 0.7% but it did not help. Under these conditions
it looked like he is getting more spots and they also grow
larger. They do fall of the fish leaving scars with a little
bleeding. The new spots will appear mostly on the old wounds or
close to gill covers. I have three black tetras with no signs of
disease, so it either something specific to gouramis or the
parasites are not leaving the fish?
As far as the treatments I've tried so far: 2 weeks of raised
temperature plus salt-did not work; 4 treatments with parasite
clear tank buddies by Jungle lab (Metronidazole, Praziquantel,
Diflubenzuron, Acriflavine) 48 hours apart with 25% water change
- did not do anything; Seachem Paraguard bath for 1 hour - took
most of external spots down. At that point I collected all that
stuff that come from the fish and looked at it under the
microscope. What I found was a few Trichodina like
<Can you describe these? Size?>
a tiny microscopic worm (likely nematode) that was still alive in
the Paraguard water and tried to wiggle himself back into the
piece of dead skin-Ouch! Another creature was a tiny insect-like
thing (six legged one), but may be crustaceans of some sort.
What a zoo and I'm still not sure what is going on.
I had to repeat Paraguard bath for two more times to take care of
the few leftover spots that would keep reappearing on the fish
skin and now his skin is clean and keeps healing well.
I also added the recommended amount of Paraguard to the tank
water every 24 hours for 3 days until The ammonia level raised to
.25. Damn, I trusted the Seachem for being filter safe and here
I'm. Did 50% water change, ran carbon with Nitrazorb and
added Prime and good squeeze off my established tank sponge. By
the end of the day the ammonia level was 0, and the rest of
parameters were all fine. That same day Gourami felt itchy at his
gills, he would go to the surface, inhale some air and blow the
bubbles through his gills. After doing this a few times I found
a worm dislodged from his gills. That worm is about 1 cm
long, and ~ 0.5-1mm thick, white-transparent looking. Has a
ventral sucker and may be dorsal sucker, half filled with blood
and other thicker half filled with some yellowish stuff (organs
or eggs). Could it be fluke?
Could they be so big?
<Rarely, but yes>
After that worm fall of the fish's gills the Gourami is not
eating, just takes the food and spits it out. Also not as active
as he used to be.
I'm sorry for such long email, just wanted to include all the
I'm extremely desperate to save my fish, but feel that these
past 3 months were really stressful and I'm at my personal
water change limit.
Please, if you could help me to find the proper treatments for my
fish I would so much appreciate this.
<I'd go back w/ an Anthelminthic... the Praziquantel by
itself. Please read

Re: Parasites on three spot Gourami.
Thank you very much for your reply and all the info.
What I thought to be a Trichodina-like parasites, were round
single cell organisms of ~ 20-40 micrometer in diameter, some
were quite transparent with identifiable edge and some sort of
fluff around it, which made me think It could be cilia. Since
they've been seating in Paraguard treated water o/n, they
were dead and not moving. Other type were also round, but more
brownish in color (no horseshoe-shaped nucleus), but similar in
This morning one more worm came off the Gourami's gills and
it looks nearly identical to the one I found before.
I looked at both of them under the microscope and the closest
look-alike organism I can find was Schistosoma sp. (I have
attached the image I found on the Web as well the photo I've
taken). Sorry, for the poor quality, It was taken with phone
<These look like flukes to me, with their prominent hooks...
definitely worms of some sort>
I also included few pics of my fish with those raised spots.
Could it be some sort of Trematode lifecycle form
I don't have any snails in the tank, so if indeed these
things are flukes, could they have fish as the only host?
I guess my hopes are that those worms may be do have some
intermediate host and the whole thing will just die off
eventually, if they can not complete the cycle.
<You are correct, if they have a complex life history>
I have ordered some Hikari liquid PraziPro, thank you very much
for your suggestions.

Blue Gourami Question Hello. Recently bought a 55 gallon
tank, and got a variety of fish. <Greetings> 4 silver dollars 4
glass tetras 4 high finned tetras and 2 blue Gouramis I also have a
Plecostomus <OK> Everything was working fine, until I noticed Ich
on some of the fish (silver dollar and tetra). I treated the water
following the instructions, and still notice a white spot on one of the
glass tetras. I hope this resolves itself, but I worry about one of my
Gouramis. He lives around the plants, which is near the filter. He has
been fine there, but now he seems to be caught up in the current. He
tries to swim, but just lurches forward and back. The other Gourami
chases him sometimes, and then he can move just fine... I'm worried
if that is a problem with the Ich, or something else. <You may need
to re-medicate for the Ich again. I really don't think the Gourami
has a problem, most likely he just likes that spot and the feel of the
current there.> Ph is set at 7 and I've been pretty regular on
changing the water, although I haven't tested the ammonia. Any
advice you have for a new fish hobbyist. Adam Sutherland <You
probably should test the ammonia and nitrites but other than that, keep
up the good work! Ronni>
Yellow or Gold Gourami has spots
4/21/07 I'm hoping someone can help me. I have a fairly new 46
gallon freshwater tank that has an assortment of silver dollars,
<Mmm, some of these species get quite large... please see
fishbase.org, WWM for the genera Metynnis, Myleus, Mylossoma...> 3
kinds of Gouramis, tetras, head and tail lights, black barbs, pictus
cats and a plecostomus. I have had the tank for over a month and was
adding some new fish to the tank, as I was about to put a new yellow
(or gold) Gourami in the tank I saw he had spots on his top fin and one
side of his body (right behind his gill). Instead of putting him in the
tank I put him in a ten gallon quarantine tank. <Good idea for all
such newcomers...> Originally I thought it was Ich so I treated it
for that but no change other than the spots have gotten larger, more
like little clumps. it hasn't spread anywhere else on the body but
those spots seem to be more noticeable. He's active and no other
problems, but I don't know what to treat him for. I've looked
at so many pictures of diseases and it doesn't really look like
anything I've seen. I want to say that the spots almost have a
light bluish tint to them but that could be from the treatment for Ich
I was putting in the tank. Any help is greatly appreciated. Heather
<Mmmm, might be encysted worms, Microsporideans... other such
organisms... You could try an Anthelminthic like Prazi... perhaps
followed by an anti-protozoal like Metronidazole... Both materia medica
are discussed on WWM. Bob Fenner>
