Description: My 75 gallon as of now has a dual HOB Biowheel filter and an air tube along the back of the tank. The fish inside are angelfish, a needlefish, a peacock eel, an iridescent shark, two algae eaters, and other fish that will be gone soon. A couple of angelfish have just layed eggs in my tank as well!!
Advice: just take it easy and be patient as things are not always immediate. Don't always listen to the petstore, get advice from real hobbyist like from online forums, they can be very helpful.
