Please email me with your suggestions I currently only have 3 fish in fully operational aquarium. My last experince buying fish I belive I got to many to fast. Luckly there appered to be good water quality. So nobody at the petshops good tell me what was going wrong. I managed to keep 3 fish alive and well. They have been living in the tank by themselfs for about 2 months. I belive that it is time I got some more fish. I have currently in my tank 2 zebra danios and 1 albanio cory cat. My first choice was to get some guppies but don't know if they will work with the fishes I have. What fishes do you suggest?
