Are Discus Fish Hard To Keep?


Discus fish are one of the most popular tropical fish in the hobby.  They are known as the “King of the Aquarium“.  The ultimate goal of most fish hobbyists is to keep Discus Fish.  Discus fish are not cheap like your typical freshwater fish.  Before investing in discus fish you must ensure that you do your homework to make sure that your hard earned money is not wasted.  It is best to purchase discus fish directly from a discus fish breeder such as Wattley Discus or DiscusGuy to insure that you are getting healthy and good quality discus.  Try to stay away from sellers who only just resell discus.  The quality of their discus is usually not good.  Make sure the seller has breeding experience themselves as they will know all the tricks to the trade needed to keep healthy discus.  Also, check their customer reviews.  Don’t be fooled by prices.  The cheapest fish are not the best and neither are the most expensive fish.  Look for prices in the middle.  You get what you pay for – most of the time!  If the price seems too good to be true, it probably is!

Discus fish are not as difficult to keep as many people think.  Discus fish require warm water between 82F to 86F.  Most tropical fish do not do well in those high water temperatures so you need to check if your fish are compatible with Discus Fish.

Discus fish require a varied diet.  Their diet consists of flake food, beef heart, blood worms and pellets.  Most of the same foods that any other tropical fish will eat.

Aquarium size is one of the most important elements of keeping discus fish.  You must have 8 to 10 gallons of water for every fully grown discus fish.  Failure to do so will result in the fish not growing properly and becoming an odd shape.  The right sized tank is critical.

Discus fish are schooling fish.  They travel and feel safe in groups of 6 discus or more.  You cannot keep a single discus by itself as it will not survive.  The larger the group of discus the better.  You can keep different discus strains together without a problem.

Water Changes

Water changes are crucial when keeping discus.  Discus need very clean water.  As a result you need to be careful not to overfeed them.  Feed them 2-3 times per day as much as they will eat within 10 minutes.  Siphon out any uneaten food.  Perform 30-40% water changes at least twice per week.  The more water changes you perform the faster the fish will grown.  Also, the more water changes you perform the more likely the discus fish will spawn!

As you can see, discus fish are not that difficult to keep.  Just make sure you have a good maintenance and feeding routine in place and do your homework before spending your hard earned money!
