Hello MFK members, I need some help with my new jardini arowana. I took him home 3 days ago and he is in my 20 gallon long which was my QT tank while im Cycling a 210 to be my first monster tank. He is 6 inches long and seems to be healthy for the most part. However as a QT tank I did not have lightning on it and I just installed one this morning, however almost immediately after I turned on the light he started rubbing his face against the glass. He isnt showing any signs of ich or velvet and I see no growths on his body of any sort. The only abnormality is a few missing scales because according to the store he jumped out of the tank about a week before I bought him. But back to the rubbing, since it started almost at the exact same time as me turning on the lights for the first time, do you guys think it could just have something to do with seeing his reflection? I hope thats all it is and maybe Im just overthinking because I dont want to loose my brand new $200 fish. Would it be a good idea to just treat him with parasite medication for a few days just in case? I just need some opinions and help please. Thank you in advance to anyone who can help
