I have a 250 Litre tank, nitrates are about 50-70 ppm, our tap water is 50ppm so getting lower isn't feasible.
Nitrites & Ammonia is at 0ppm, Ph is in the high 7 or around 8, hard to tell just from comparing colour charts exactly but it's definately a higher PH by a little than what comes out of the tap at 7.6 recently, my water temperature is 26.5c. Really can't see it being oxygen related as it's been fine for months with 2 large airstones, 1000lph spray bar & 1000lph power head moving the surface. Substrate is sand and the tank is live planted.
Tank inhabitants seem to keep dying at a rate of 1-2 fish per day, it started when I added a few Dwarf Gourami, one of which died 3-4 days later.
Zebra Danios were hanging around looking like they are constantly nibbling & some were red around gills & anus, also lost some Kuhli loach, many of which look like they are gasping saw 2 last night sat on top of the powerhead with their heads at the surface, 1 is dead this morning, some of them when I can see them are pink around gills, some of them seem to have partially lost their colour along their lower halves.
A friend suggested praziquantel which I added on Friday at about 2pm and whilst I was at it I caught all the Danio I could (5 of them, 2 were too fast) and put them in a spare unheated tank with 10l of transferred water as I know they can tolerate room temp water at about 21c, one had a torn tail and another had some odd things going on with it's eyes like they were white & bulging or covered by something. The one with the torn tail appears to have stopped the nibbling behaviour and actually recovered whereas the one with the eye issue died that night, although the eyes appeared normal when I found it. The 4 remaining Danio are now chasing each other about like Danio do and no longer have any symptoms and are frenzied eaters again when food goes in.
Since Friday I lost 3 more Kuhli, two of which I saw frantically swimming around the surface & resting on the powerhead mouthing the surface at about 2am, they were dead by 8:30am. A Danio has disappeared somewhere & another is gasping and really lethargic, don't expect it to make the night.
As far as i'm aware in period of 7 days if this Danio dies i'll have lost -
6 Zebra Danios out of 10, the only survivors being in the seperate unheated tank
4 Kuhli Loach out of 8 but I haven't seen any now for a few days so it could be all 8 of them
1 Dwarf Gourami out of 3
All 4 of my Otto Fish are still going, my Green Phantom Pleco is still doing his thing under his bogwood but I never see him out so hard to tell how he is, my Vampire & Amano Shrimp also all seem fine.
Any ideas besides the praziquantel? I don't want to just throw random meds in & I also don't wanna kill the shrimp, especially not the Vampire.
