Going to be housing some Barracuda in this tank, maybe a Payara, maybe an African Pike... We'll see how it goes! So far I only have one Aquaclear 110, but I plan on adding another soon. There are just 4 guppies (3 of which are female), 2 Cory cats, and one ghost shrimp in there. Once my house is done being remodeled I will add the carnivores, don't want to freak them out with all the house work going on. All that's really left for me to do is paint the back and sides black, night light, AC 110 #2, and a little more decore. Sorry for the bad pics, still getting used to the camera. Oh and those are bubbles, not scratches. Let me know what you think!
