Type of fish: royal whiptails (all 4 deceased), German Neon Blue Rams (only 1 left), Boesmani Rainbowfish (lost 1,1 still suffering). Asst Guppys & Harlequin Rasboras seem to be unaffected.

Symptoms: lost body condition, started with whiptails and rams, then had a mass die off. Could see little red worms coming out of the anus of the remaining rams and rainbows, after 3 weeks of treatments onky 1 bosemani has protruding worms but i lost another rainbow yesterday, 1 female guppy also seems to be loosing condition

Other tank mates: yoyo loach, khulis, some ottos and about 60 baby guppies

Tank size / capacity: 4x2x2 rimless thickly planted tank.

Type of Food fed: NLS Thera A Mini & NLS Small Fish formular, treats of freeze dried black worm, hikari algae/shrimp wafers.

Feeding frequency/amount: fed once a day, fasting on weekends except for some algae wafers

Substrate: eco-complete black planted & some white sand
Type of filtration: fluval fx-6 filter with standard foam plus 1L matrix and some fine white wool, inline 300w eheim heater and a 36W uv steraliser (switched off for 48hrs following a praziquential dose or duration of a sterazin course).

Frequency of filter cleans: inspected monthly, usually partial clean of wool, rinse the matrix with tank water OR rinse foam (never both in the same month)

Frequency and % volume of water changes: 40% a week or 50% a fortnight depending on work. I did a different schedule during medication treatment, 48hrs after a prazi dose I would gravel vac as much as possible and remove 50% of the water,1 week later redose and follow the water change regime again. When I was dosing Sterazin I did the course for a fortnight and then did a 50% change.

Last water change: last monday, due tomorrow.
PH:7.4-7.8
KH: tapwater is 6-9 (changes each week), i bring it down to around 4-6 with seachem acid buffer (phosphate free).

GH:6-8, changes from week to week, I dont dose calcium or magnesium in my fertilizer regime, so by the end of the week the gh tends to have dropped.

Nitrite: 0 checked with two calibrated test kits
Nitrate: falls to 0 with plant growth, i keep it around 5-20ppm
Ammonia:0 checked with two calibrated test kits
Phosphate: falls to 0 with plant growth, i keep it around 2-5

Water temp: heater is set to 26, this time of year it sits at 27-29

Medications used recently to date:
3 weekly doses of praziquential in addition to a 14 day course of sterazin


Any recent changes..new fish/filters/power outages etc etc:
Added some new plants 6 weeks ago, aside from that nothing new had been in the tank since July when i added some rams

I have tried everything I can think of, I have heard that Kusuri Discus wormer is meant to work wonders but I am struggling to find some without having to wait for it to be shipped, if anyone has any suggestions that would be fantastic.
