Just tonight I had to euthanize a Gourami in my tank (an Opaline I believe). Less than two weeks ago, his fin started to rot very quickly. I dosed him directly with Methylene Blue and then did a water change. I kept a close eye, thinking it was just fin rot. It quickly spread into his stomach and started eating the skin. Today I found him bloated and side floating, looking almost like he had dropsy. The big chunk that was missing is what concerns me. Well, I scooped him out, and he didn't hang to close with my other gouramis, so I'm just watching them... Today, my favorite male, a pearl (soooo gorgeous) has a small pink bump right above his eye. It doesn't look like a gash, just a bump with no scales. If his face rots off I swear, I'll cry! Advise? Maybe this is a Prazipro job? Or any idea what that insanely fast rot on my other Gourami was? HELP! I know that these guys are super touchy with disease, and I'd hate to lose my whole Gourami tank... Not to mention my cats, etc! :|
I just tested this tank not an hour ago:
pH - 7.2+
KH - 6
GH - 9
NO-3 - <40 (I know it could be better, I'm doing a 25% tomorrow, and did one on Monday)
NO-2 - 0
NH3 - 0
No issue there that I can see. I do water changes at least once a week, twice under disease conditions.
Any more ideas anyone?
See if this helps!
Fish Disease and Treatment
Found it... I think, I really hope it helps.
Head and Lateral Line Erosion Disease (HLLD or HLLE) - Hole-in-the-Head Disease
Symptoms: Begins as small pits on the head and face, usually just above the eye. If untreated, these turn into large cavities and then the disease progresses along the lateral line.
Head and Lateral Line Disease is also known as Hole-in-the-Head Disease, Lateral Line Erosion (LLE), and Lateral Line Disease (LLD). It is attributed to a nutritional deficiency of one or more of: Vitamin C, Vitamin D, calcium, and phosphorus. Though its cause is not definitively determined, it is thought to be caused by a poor diet or lack of variety, lack of partial water changes, or over filtration with chemical media such as activated carbon.
HLLE has been reversed by one or more of the following treatments:
Increase frequent water changes.
Add vitamins to frozen foods.
Add the addition of flake foods, as they are enriched with vitamins.
Add greens, either frozen or in leaf form, to the diet.
Decrease the amount of beef heart as it lacks many critical nutrients.
Remove activated carbon filtration.
(This disease is often confused with another disease called 'Hexamita', because both these diseases are often seen simultaneously in the same fish. Hexamita is a protozoan disease that attacks the lower intestine. Discus and other large cichlids, especially Oscars, are especially prone to Hexamita.)
I really don't think this is hole in the head. It looks like it's increased in size a bit, but not much. I wonder if it's just a wound, but it looks like it's poking out, not gashed in. It looks kinda puffy. I've been dosing the tank with professional strength melafix, aquarium salt and stress coat. Well, hopefully it doesn't get worse...
Dump the Melafix. Remember you are dealing with anabantids so the melaluca concentration can kill your fish. Do another water change to remove it. I do not advocate the use of Melafix. It works in allowing the wounds to heal fast but it will do nothing to a bacterial infection which I suspect your fish actually has.
Do you have kanamycin access?
How much salt was added?
Ditch the stress coat as well.
Wait, I've never heard about melaluca killing Anabatids. Can you elaborate please? I don't understand why melafix would not help hold back bateria when that's what it's for... :question:
I've used Kanamycin extensively over the past year on several different kinds of bacterial infections with only minor results and lots of losses. Have you tried Aqua Pro-Cure?
I added 1 tsp per 5 gal as directed on the salt, just once after the last water change.
Ditch the stress coat? I'm not sure why that would be a good idea. Perhaps you can provide more information as the reasons for your advice? Much appreciated!
No, it does not. It can help allow recovery of the wounds faster than normal but it does not really hold back bacteria despite its "antibacterial" claims.
Bettas and gouramis breathe air even from the surface. They are far different from the normal aquatic fish so any herbal med, especially aloe vera, that can suffocate the fish will kill them faster than it would to a "normal" fish. Add to that the fact Melafix allows too much slime coat production that the excess could get trapped in their respiratory system and suffocate them in the process.
I haven't tried Aqua Pro-Cure. What are the active ingredients? Not familiar with this product.
What other antibiotics did you try before?
You have access to Maracyn Plus?
Well shoot. Do you think it still makes sense to add some when adding new fish to help smooth the transition?
I guess I figured the labyrinth breathers where more hardy given the fact that the labyrinth system is designed for low oxygen water, is it not? Weird. Well thanks for the info. I guess I'll stick with my Prime for water changes instead of stress coat. I've seen stress coat do some amazing things though, so I still love it!
According to the MSDS:
Water 88 - 91%
Formaldehyde 4 - 6%
Methyl Alcohol <1 – 2%
Acriflavine Hydrochloride <2%
This medication is mostly designed for parasites but is also highly effective against bacteria. According to a study I read on fin rot and scarlet this stuff is highly recommended, especially since it does not hurt inverts (that sounds nice, but doesn't matter for this tank).
