Hello again, i was planning to get some dats, and i got 3 indos about five days ago about 2 inches long (30 gallon tank). They seemed to be very active and curious. 2 of them seemed to be stable due to bright stripes while one seemed to be unstable due to dull stripes. The unstable one is the most active and chased the other 2. A few minutes ago while i was looking at them, the unstable one chased the other and hit him, and in like two seconds the dat being chased started to swim in circles like fish do when they have that bladder infection, it was weird and in instant he died, no breathing what so ever. Now hes chasing the other, why is this happening? although there are many hiding places. Should i separate them?
Thanks
Thanks
