To the left is Jack. Jack is a Jack Dempsey from the Yucatan Peninsula. He is an Omnivorous fish, and will reach between 8 and 10 inches in length when fully grown. He stays in ~76-78 degree water at 6.8 pH. He also receives 25-35% water changes Bi-weekly. He's fed a diet of Bloodworms, baby shrimp, and Hikari Cichlid pellets. Jack is a very smart and beautiful fish and I love watching and taking care of him.
This is my DIY CO2 diffuser... I made it for about $7.00 I bought a pencil holder at Walmart that has swinging drawers to put items in. I took the three drawers off and drained the tank. Next through trial and error, with the tip of a pen knife I made a small hole in each of the two lower drawers just big enough for the CO2 gas to pass through. The air line is routed down to the lowest drawer. When the gas builds up enough pressure, it blows through the hole and up to the next level. This is demonstrated in the bottom two pictures. The three plastic hemispherically shaped cups are held to the glass with double sided tape. I drained the tank and wiped the glass dry to mount them. So far, it appears to be working well.
