We would really appreciate some advice!
We recently purchased a 20 uk Gallon 80 Lt tank, we cycled it before adding fish using quick start stuff we bought at the fish shop, left it for a week then started adding fish over a period of 3 weeks with no problems.
The tank is a jewel and has a 4 stage filter, we tested the water before we added new fish and then every couple of days and all levels remained within normal rangeÃ¢â‚¬Â¦
We ended up with:-
2 x Dwarf Gourami
2 x PlatyÃ¢â‚¬â„¢s
2 x Rainbow Fish
2 x Black Mollies
2 x Sword Tails
5 x Female Guppies
5 x Male Guppies
Total 20 small fish which we were advised would be fine in a tank this size.
Aprox a week after adding the last fish we fed them some live food for a treat (we bought the food from the local aquarium shop which has a good reputation.
Then it all went wrongÃ¢â‚¬Â¦..
1 Gourami died 3 days later we tested the water and the ammonia had gone through the roof. We did daily water changes and 2 days later lost the other Gourami, I know this is because of the ammonia problem as I was told they are sensitive.
By then the water had sorted itself out and all levels were back to normal, then the guppies started dying for no obvious reason we have lost 1 a day since first all the females and today we lost a male. There is no obvious sign of illness although they act strangely swimming at the top of the tank and the next morning the fish is dead. None of the other fish in the tank are effected
