If you want them to display a darker color, then keep the bottom and background colors dark to black.

Discus Fish Grow Faster in a Smaller Aquarium
Return To: How Many Discus Fish Can I Put in a 100 or 55 Gallon Tank

My belief is that they have an abundant supply of fresh water and food, which in

Do Discus Fish Mate for Life
Return to: Discus Fish Sale *The short answer to this question is no. What

vicinity to take interest in her spawning activity. It does not take long for
one or two males to take interest, at which point territorial disputes might
break out between all involved. Once things calm down a dominate male will
emerge and start the ferti

Best Aquarium Filter for a Discus Fish Tank
Return to: Featured Discus Fish *I have tried many freshwater
aquarium filtration systems, from expensive wet-dry to inexpensive air driven
sponge filters. I must admit, for the hobbyist that has one to just a few aquariums,
the hang on the back filters is by far the easiest and will last the longest.
Some of my hang on the back filters are still running after 40 years. So, for an
inexpensive $30 investment they have paid for themselves many times over. There are several brand names to

Lowering pH in a Discus Fish Tank
Return to: Discus Fish Sale *Discus fish like acidic water conditions, and your aquarium

neutral and into the acidic side will reduce bacteria. Acidic water on a
molecular structure will convert toxic ammonia NH3 to a non-toxic form of
ammonium Ion NH4. Aquarium ammonia testing kits will still read ammonia if
