I just bought 6 (2.5″) Discus, it’s been a week & they seem to be afraid by hiding at the edge of the tank behind the filter, so it’s quite difficult for me to enjoy the show & feed them.
Do you have any tips how to make them feel comfortable in their new home ? I feed them with beef heart, even I try some bloodworm they are still afraid.
My tank is 100x50x35 cm, and only Discus inside no other fish.
They are definitely not happy. If your discus is always hiding, staying in a corner, easily frighten and not going for food when feeding, most likely they are not happy with its surroundings.
You need to find out the reasons and help them:
1. Positioning of aquarium. Vibrations caused by people opening and closing doors, walking up and down the stairs make the fish jumpy and slow to settle down. Put the fish tank in a light traffic area.
2. Fish does not like shadows. It will frighten them. Setup an overhead lighting on the aquarium. The fish will feel better. You can see them better but they cannot see you. All aquarium shops have lighting on their show tanks. The fish are not scared with all the people looking at them.
