Hi Guys,
My kids have an aquarium at home medium size which has got a filter and they are changing the water and cleaning the whole stuff occasionally but not late. They are feeding them morning and evening according to the instructions from the pet shop. They have to buy new fishes in every two months as most of them are dying. They were using marble pieces to decorate. Some of our friends told that the fish will die if we use them so we changed it to clean sand and real stones. We are growing some real plants as well but vey often the fishes especially the smaller varieties are dying faster. I would appreciate if someone can help me to solve this problem.
