I wondered if anyone has any advice for me, i started up a tank in march (30 litres)and brought 2 fish 2 weeks after, these then died 1 by 1 within 2 months, i then brought another 2 fish beginning of june and they are now both dead ;( what am i doing wrong??
i was told by the aquariums that the water was fine to put my fish into it (it was tested a number of times)
i have now been advised that 2 weeks was not along enough and should have left the tank for at least 6 weeks and i have also been told that a 30 litre tank is not big enough... why do they sell them then? ;/ i have also been advised to test my own water in future, i would really like to keep fish but cant really afford a bigger tank!! HELP! xx

Thanx for the reply,

The first 2 were globe eyes and the other 2 were a ryukin and a fantail, all babies. What do you think i should do now as would love to get more fish.

Just wondering if anyone can help me...

i got a 30 litre fish tank in march and added 2 fish 2 weeks after having the tank, water was tested and levels were fine. About 2 month after having the 2 fish 1 started floating and generally not looking very well and then it died and then about 1 month late the other did the same. I then did a water change and was told levels were fine (i went to a different aquarium) and purchased 2 new fish. 1 has now died and the second is on its way out... what am i doin wrong!! please help!! thanx
