Parasites? Help

[Em29]

My Dwarf gourami, two corydoras have died. My female gourami has an ulcer won't be around much longer though is still feeding. I have only been able to get Interpet Anti-Internal Bacteria at the moment.

I haven't seen any worms but who knows.....I am shooting in the dark here. Water stats are perfect and the tank has been all good since it was fisless cycled 3 months ago.

Now I am losing my fish and have no real idea as to what is wrong other than the fish seem to get emaciated, pale, white stringy poo and the go upside down and die over 2 days.

This points to parasites yes?

I have a 90l tank
6 leopard corys
4 platies and fry
female dwarf gourami

Can you please post your water stats?
Also brand name of test kit?

Having you seen any worms sticking out of the fish anus?
Check all your fish for enlarged anus. Red inflamed anus?
Do any of your fish show signs of a curved spine. S shaped spine?
Have the fish lost weight due to not eating?
Have any of your fish been bloated?
Do any of your fish sink to the bottom of the tank?
So any of your fish lean to one side resting on the bottom of tank?
Do any of your fish have sunken in bellies?
Have any of your fish have bulging eyes or swollen eyes?
Have you seen any signs of fish flicking and rubbing on objects in the tank?
Do any fish dart around the tank?
Any signs of erratic swimming?
Do any of your fish swim in a jerky movement?
Check your fish for greyish film on body, fins?
Are any fish producing more slime, or trailing mucas from body, or fins?
Do the gills look red and inflamed?
Do the gills look pale, with excess slime?

The ulcers you are treading for. Are they red, or pink, with a circling of dead white tissue around the edges?

Sorry for all the questions. Just need to rule somethings out.

Thank you so much: Here goes:

Fish sink to the bottom, lean onto one side, their spines curved at the tail end.
I cannot SEE anything from the anus.
They go paler in colour
Gills are paler
Bellies are sunken
The female dwarf Gourami has a circular red lesion (no white edges as yet)
NO greyish film No bulging eyes.
No jerky swimming/ rubbing against objects
Feeding well
No bloatedness
No slime trailing but before the Male Dwarf gourami died lots of clear/ white stringy poo for 2 days.

The fish with the curved spine were they old?

All you can do really is worm your fish.

You need to use a good bacterial med like furanol 2 by JBL. It will knock your good bacteria in the filter.
Do you have any other mature tanks. Which you could take some mature sponges from to kick start the tank again. Once the medication course has finished.
Also internal wormer med called sera nematol.

The symtoms are pointing towards.
Bacterial, fish tb, internal parasites, with secondary infections.

Thank you wilder - no they are not old fish at all. I will be treating them, unfortunately I do not have any more mature filter material. I will have to be prepared to go through a mini cycle. fish in and do some daily changes again. Good grief. I am gutted.

There are some members who donate mature filter sponges to members. Just go and see if I can find the thread.

Here the list.
