Awesome video im about to get a 75 gallon discus tank, any suggestions?

Thanks.. and appreciate the feedback! But 4 Discus for a 72 gallon tank would be a bit..sparse. 18 gallons of water for each Discus? Definitely not required. Discus like to school (as do the tetras and loaches) and tend to occupy defined areas of the tank at any given time. I've actually acquired more Discus and Tetras since this video was posted (see update video), and the new fish have really helped reduce the aggression in the tank. But every tank is different, so maybe I've been lucky!

I just got a fluval 306 for a 20 gallon high and I have an FX5 on my 150 gallon high...... over kill is always better regarding filtration, so props...looks good, but small for that many fish....... 4 discus alone would be to much for a 72
