my 6 inch arowana is barely swimming and he seems really weak. He was fine this morning but when i came home hes really weak. I dont know what to do i cant test the ammonia or ph level cause i was planning on buying to tmrw. I just moved him into a new tank and i put in "prime" to remove chlorine. he was living in a 30 gallon tank, i know its small but im waiting for him to get bigger to get a new one, he now sits in a 10 gallon tank. PLEASE HELP ME
