A Week Of Dying Fish

[doresy]

Ok, so all the info first....
Tank...AquaOne 850 (155ltr) with canopy filter with improved contents
Running stock since December last year (after cycling)
No new stock for over a month
Heavy (real) planting
Latest stats (constant) Amm0. Nitrite0. Nitrate40. Ph7. Temp. 76*
Water Canges.....25% every 6 days with grav. vac.
Stock (left) 5 cory, 1 sae, 2 platy, 2 neon tetra, 4 female guppies, 2 male guppies, 1 male neon d gourami, 2 female neon d gouramis, 6 harequines

History
...Saturday- 1 dead Harlequine (fish looked fine other than being dead!)
Sunday- 1 neon tetra swimming nose down but still feeding.....Added Interpet No. 9 Anti-Internal Bacteria treatment
Tuesday- Neon tetra dead (again no visable problems)
Thursday- second dose of No. 9 treatment as per instructions
Friday- Sudden death of 1 female guppy (fish looked perfect) Also noticed red wort like growth (to the left side of mouth) on male N D Gourami.
All fish (incl. worty gourami) acting normally and feeding.

Have just done a 25% water change... thinking of adding carbon to filter to clear old meds.

My main concern is the male Dwarf neon blue gourami with the red wort growth.

Any comments welcomed

Want to just check the neons first, have they lost any colour in the red stripe.
So the anti internal bacteria med did nothing for the wart on the mouth.

The red stripe on the neons is very strong in colour. The wart on the Gourami's mouth was only noticed this evening although he has been hiding and coming out for food late all week which is unusual!

Look under growths on skin.

Does the growth on the mouth look like anything like this.

No not really, its a single white and yellow wart which is red at the base. Have been reading the gourami forum (should have done that first ) apparently this is a very common viral condition in dwarf gourami usually resulting in death

I am not sure if my deaths are connected. My water is good so I'm not sure

 

[WILDER]

If its viral there no treatment and yes it could affect the others sorry.
