hey whats going on guys? just want to say what's up from Boston. i'm relatively new to the aquarium hobby. decided to join the forum, hoping i can learn from everyone that would take their time answering any questions i may have. i'll greatly appreciate it! i have a 55g long with a 3.5-4inch black arowana, a few 3inch leopard ctenopena, 3inchgold datnoid, 5inch polypterus delhezi, 3inch polypterus endlicheri, 3inch multipunctatus synodontis, 4inch L075 peckooltia sabaji, and 2x 2inch clown loaches. i WILL be upgrading to hopefully 200+g tankas soon as my fish start growing out of this tank.
