I don't know how many of you remember me, i left the forums about a year ago, but I am thinking about putting my old terrerium to use by making an aquarium. I have very little knowledge about this, but it seemed like an interesting idea. I basically need to know where to begin. My tank is a 20 gal long, i dont have a suitable cover or light for it. I wanted to know other things such as maintenence (how often and for how long), costs, and also, i am interested in what other things can be kept in it besides fish (i.e. crustateans, mollusks etc. im not sure about this for fresh water).
And thats the other thing, fresh water and salt. What type of fish can each support?
Anyways, its good to be back. Thanks in advance...
