Hello,
this is my new discus tank, it's a L shape tank 500 liter and it was used once as marine and then chiclid
now it has 6 discus (3 big and 3 small), and 11 cardinal, 4 upside down catfish , and 2 pleco
for the 3 big discus, there is a boss and the second is the blue 9they both moving together) and always hit the other big one
you see them in a picture
for the small discuss, one is always hide and the other 2 hit each other
i tried the sexing way of discus using geometry and i think the 2 big discuss with same color are males and the blue one is female
all your suggestions are welcome
i feed mainly blood worms, a recipe of mine (shrimp and beef hurts and liver), and flakes and a specific food of discus from LFS
thank you
