cleaned my fishtank out because of slime and pondsnail reproduction overload, also i needed to do a weekly waterchange, and i had to clean the gravel, so far allthough my fish were ok, the water was bad and my biological filter dont seem to be working properly , so i put my fish in a clean fresh water quarrentine tank the water was a little cold but the heater was in there for about 20 minutes before i put the fish in there and within two hours iv lost m white molly, my glofish, my blue neon tetras and my silvertipped tetras, then i added my guppy ry and all of them are still alive so far bt the only fish thats living now are 2 platys, 1 pleco, 1 guppy(adult) 1 sucking loach most of my molly/guppy fry and 2 dying silvertipped tetras and 1 dying green tiger barb, im bloody gutted all the money ihave spent on fish and after 1 month the buggers die >(

i have gotten rid of my plants because they were turning brownish black at the bottom, and when i went to take my fish out my molly was covered in loads of slime

i admit i have overfed my fish thisweek m trying to make sure my fry get plenty to eat


3-4 hours later 14 of my fish have died:(

what size tank? Only set up for a month? Did you use established benificial bacteria to kick start your cycle? What kind of pleco? Were you using a test kit to monitor your water values? Did you use a water conditioner to remove chlorine, chloramines and ammonia?How often are you doing water changes? water quality from the old tank to the qt could have been to blame, but it's really too soon to say for sure. Take a deep breath, we all have fish die at one time or another, and we've all made some kind of mistakes at times with our tanks. Answer the questions, include substrate type, and verify how long it's been set up. what kind of lighting for how long? what types of plants? we should be able to get you through this.

wooooow too many questions lol, my nitrite in my 90ltr tank was high, hence the water change as well, my 90ltr tank has been set up for about 4 months the i dont know the PH cause i ran out of tests and i have aquael Sunnyday t5 lighting energy saving light andi have a good filter god heater i do use water condidoner i use the interpet aquarium starter ki, which is fresh start and filter start and also i have been using whitespot remover,but put that in my big tank a week ago.

the qt tank is my 30ltr, and considering all my fish are small they were only in the QT tank untill m other tank is sorted, but the water tempreture must hve atlat been between 20 -24C and now the temp is on full 28C now my pleco is a comman pleco and he is 3 and a half inches long

the fish that are offiially dead are
5 x blue neon tetra (0.5cm)
5 x glofish (1.5cm)
2 x silver tipped tetra (1.5c)
1 x green tiger barb (1cm)
1 x white molly (3cm)
the fish were quite small and its really wierd th al my fry are alive, when my fish were dying they were all on the floor on the sides looking paralised but still breathing, but later on then they were stiff as a pokerand my other fish are all fine which are
1 x pleco
1 female guppy adult
2 female platys
1 sucking loach
3 silver tipped tetra
and my guppyand molly fry about 27 guppy fry 6 molly fry

baffling and annoying at the same time
My QT tank was set up properly to mde sure water was conditioned and nitrite level was ok wich was about 0.3mg or somthing lke

i do a weekly water change every week normaly but for th past 3 weeks i have been ill but cause i have been feeling more up to i to clean my fishtank this happens, either that or when i was cleaning the QT tank out about 2 weeks ago because my gupp/molly fry hve been in there for about 4 weeks ready to get big enough to put in the 90 ltr tank, i cant have cleaned it properly
 
Common pleco is going to get way, way, way too big for a 90 litre (23ish gallons) tank. Rehome or return him as soon as you can. He will grow to 12-16" eventually.

You were severely overstocked, especially with mollys and guppies that'll breed like mad, with nothing much big enough in there to eat the fry. Consider this a learning experience, take a step back as others have said, and use this time to figure out what should really be in your tank in the first place.

i have had him for a year and a half now since he was 1.5cm h was in that 30ltr tank since i had him but then i put him in the 90Ltr tank which he have been fine, my partner bought my pleco for me for our 3 yr anaversery hes been with goldfish for a year and a bit but since january when i decided to go freshwater he have been in there since and there is no problems so far,

take a step back as others have said

i went to the petsop and specifily i asked for a pregnant molly and a pegnant guppy, the fry are only 6 weeks old there just starting to get their black spots on thier tails, cant sex them yet there too young as theres no show of a gonapodium when i did buy the silvertiped, glowlight tetra and blue neon tetra they were more or lesss juivanile sizes which were rather small

I think the problem here is that your tank was not cycled to begin with.

I actually agree with this. Just because your pleco seems fine doesn't mean it isn't stunted. Common plecos get VERY big naturally, so it's not good if they are stunted to fit a smaller tank.
I don't think SC was saying that it's bad to get fish to breed, I think they were saying it's bad because you already have too many fish in that tank, and they are going to breed out of control, as livebearing fish do, which will overstock your tank even more unless you have some plan to cull the fry.

As far as why they are dying, if you have high nitrite, that is extremely toxic to your fish, and an indication that your tank is not cycled. If it were cycled and stable you would see a nitrate level, and zero nitrite, and zero ammonia. However, I think Jannika is probably right about what actually did them in. Quick temp changes are really hard on any fish, and a heater takes quite a bit of time (around 24 hours) to heat the water. It's not like heat in a house that just instantly warms it. When you say the Bio filtration was not working in your origianl tank, do you mean because of the nitrite spike? Personally I wouldn't QT my fish to a whole different tank because of a nitrite spike. I would just do a really big water change until there was only an acceptable level of nitrites in the water, because putting them in a new uncycled tank is just going to cause an ammonia spike, not to mention the stress of acclimating to a new tanks parameters and tempretures if they survive the initial temp change or whatever it is that killed a lot of them in the first place.

I hope you are able to sort it all out, but as far as what killed your fish, I think it was the shock of the QT tank.
 
Sorry if I stepped on any toes last night -- I can be overly blunt at the best of times, but my cat had gone missing and I was in a particularly foul mood. She's found again today. :)

Ashes2ashes explained what I was trying to say very well, and I agree with her as far as toxicity vs. shock as cause of death, too.
