I have a pigeon blood discus, Marlboro red medium and a colbat Blue that is a little larger than Medium. They spend alot of time running into the sides of each other. Is this common or, are they fighting? Will it kill them? Is it bad to mix different types of discus in the same tank? Please help!
1. It is ok to mix different strains of same (Almost) sizes of discus fish together. (If they don’t fight)
2.If parents and babies are ok.
They run into the sides of each other
1. They are not fighting. They try to get help and protecting each other.
Fish tank tips for discus fish.
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.
