I always buy my fish as small babies because for one there cheaper than buying full grown versions, but it is great to watch them grow over time. My interest has grown more and more as the year has progressed, another thing I got into is growing water plants so the ecosystem can be stable which the plants keet the Nitrate levels stable which is a problem with tanks that dont have live plants in them, unless you use a nitrate balance chemical. Now I started with one tank and now I have 3 tanks filled with fish, 2 are at my apartment and one is at my room at home.
