On Sunday morning my Silver Arowana started acting erratically and swimming nervously. He had eaten some shrimp earlier in the day there was a visible bulge where the meal had not digested yet.
I turned down the tank lights but within moments he was swimming head down and soon after floating.
After removal from the tank I ran a full test of all the water with zero ammonia, zero nitrite, and less than 25 ppm nitrate. Chlorine, chloramine and Ph were all within acceptable ranges.
Is it possible to have fed too much raw shrimp to him? I had a friend tell me he had an issue with iodine poisoning from overfeeding raw shrimp.
I really lack any other decent reason for his sudden demise.
Currently he is frozen and I thaw him out later this week to examine the situation further.
