Adding RedX and YKZ Acid instead of changing the water will keep the NH3 high where they like it.  The Chlorine reducer also raises the NH3 level.  Do not make the HNO3 too high or they will get Red Rust, which is fatal.  The YKZM acid makes the HNO3 level rise.  They require only a few plants.

For breeding use ONLY Barclaya and Apogonet plants or they will not breed and the eggs will not hatch.  Eggs can be eaten by other fish, so best to remove other fish.

Ormolas eat a lot. Feed adults just over 2 spoons per fish every 8 hours.  Disease spreads fast, so isolate sick fish immediately.  Hatch rate is very low.  Expect only 1 egg per clutch.  Use a big tank.  A 100 ltr tank will hold 5 or 6.

Zirco and ZUN like to swim together.  Use many long, tall plants.  Zirco change the Omni Crystal (given by the ZUN) to a Radiance Crystal after they have absorbed all the Redixin from it.  To see this:  keep many ZUN in the tank and the NH3 low.  Mix the food, but feed more marble food than Zirco food.  Keep a couple of Quick Silver Insect accessories in the tank and a few silver plants.  After you have Omni Crystals, remove the ZUN and add more Zirco. 

The Mule evolves from the Meka Spheres and is not a fish that can be purchased.  Mules need Giga-ziga and Puffers in the tank to grow.
