Is this a good setup for Nighthawk, the first photo is the over all setup, the second one is the side view and the third is the water and calcium dishes. I use an under tank heater that stays at about 88 degrees Fahrenheit and the vines are fake. He has a warm hide and a cold hide with moss in it that’s i spray down every other day. The little box is another little hide that I can see him in. And the background is tile it paper rolls that were painted(they were left to dry for two weeks)

We have a Betta baby girl fish. We have the Marina Betta EZ Care tank. We added more water to clean it (instructions say so) and now the water is cloudy and merky. Did we do something wrong?

Recently one of my Dojo Loaches have developed a weird issue with its eyes. I have 3 others who are doing completely fine. My water parameters are based around what they need and the temp too. I did a water change as well to see if that would help but havent seen any progress and I believe it is getting worse. I'm going to quarantine it for now. What could be this be? I'm struggleing to find a specific answer for this. I attached pictures of the sick loach and one of my healthy ones.
