woke up this morning found my aro swimming very slowly and weird. his nostrals are ate out kind of like a sore and his color is weird also. I am changing 50% of my water raisung the temp to 82 and adding some salt. i don't think he is going to make it though. all my other fish are great my water parameters are perfect(nitrate 15,nitrite 0, ammonia 0) I added some seachem chemicals last night for my plants(floursh excel and flourish iron, and a pad to remove my phosphate so i am sure it is one of these thats the culprit. If he dies I am going to puke. let me know what you think. thanks
