Whatsup guys! So i have a little dilema on my hand and i dont quite know whats going on. About 4 days ago, i finally brought myself to finally pick up my long wanted porcupine puffer. My lfs had a beautiful healthy one that was is ther for about a week so i decided to buy it. After putting in my tank, he looked both healthy and happy! But after about 48 hours, he began to develop what looks like ich and loose color. I know ich developing is not uncommon when adding a new fish but im highly concerned about his discoloration! Ill post pics of him below! Anyone, please help me with what i can do to help him! He is currently housed in a 20 gallon quarantine as of today! Tank- 75g fowlr 40ish pounds of fiji rock 100 pounds of live sand Foxface rabbitfish Coral beauty angel Yellow tang Its been running for quite a while and is a very established and healthy tank along with all the other fish it! Again, any help is greatly appreciated!
