i have discus

there's couple of factors you need to take in to account when keeping them

• miminum tank size depends on how many fish
• do you want to raise juvies or buy an adult breeding pair? - 6 juvies (min needed) will set you back about £40 each or you can pick up a breeding pair for c £200
• if you want a community tank you are looking at min 300l and more maintenance
• maintenance regimes vary a lot in discus keepers opinions, but one way or another you are looking at changing 100% of water over a week, juvies will require some sort of daily maintenance, fully grown adults need less food and less maintenance
• the simplest set up would be a 300l bare bottom tank with a single external filter, good couple of heaters set at 29C in a quiet location of the house and 3 or 4 30% water changes per week
• things to google - discus varieties, 3 stage HMA, BIDKA, UKDA, Simply Discus, Discus South, Daydream Discus, Chens Discus, WRG Discus, Devotedly Discus

good luck!
