Hi friends : I have always thought I would have an aquarium but so far have no knowledge of experience of it. The thing is my dream of owning aquarium realized sooner than I thought when I bought a new house a month ago. The house has 800 gallon fresh water aquarium built in the wall. He told me there are about 150 African cichlids fishes in there. The previous owner was having it taken care by local company. The company is asking me a charge of 300-500 dollars every month to check it once a month and to bring supplies. I will d this for some time but can't afford to continue this. I like to learn how to take care of the aquarium by myself and decrease the cost. Pleas throw me ideas - anything is helpful as I am totally brand new to the subject.
