Greetings and hello... I'm stepping up from my faithful betta fish... I've acquired a nice 55 gallon tank to compliment my betta's half gallon... I'm looking to build a freshwater tank for some cichlids; perhaps a tiger oscar, a jack dempsey and maybe a pleco... I'll probably start with the 55 gallon and then move them into a bigger tank when they get big enough and then try my hand with a saltwater tank with clownfish, angels and dragonets... Well, that's a pretty good introduction... Take care...
