My fish swims to eat but then goes back to the bottom of the tank and stays there, I am treating him for ich too. His breathing is slow and steady but he just stays at the bottom of the tank. His friend died a few days ago too, could he be lonely ?

Thanks for reaching out about Nemo and including photos. There is no evidence of Ich in the photos. Have you tested water quality for pH, ammonia, nitrites and nitrates? Correct problems. If having difficulty breathing (slow gill rate) add an air stone. A veterinary visit is recommended to assess and provide a diagnostic/treatment plan. Good luck.

I went on vacation and put a vacation feeder in the tank when I came home his tank was a sandy color. After cleaning his tank complete I put him back in and after that he hasn't been the same going on a week with out eating. What did I do wrong? Now

Check the water chemistry. Confirm ammonia and nitrite levels are 0.25ppm or less and nitrates are 40ppm or less. Use a liquid test kit or submit a sample for testing. Most pet stores or aquarists will do this for free or for a small fee. Partial water changes, about 30% can be done to decrease high levels. Use only aged or conditioned water that is temperature matched to prevent further stress or shock. My preferences for water conditioning are AmQuel Plus and NovAqua in addition to StressCoat. Confirm water temperature between 78F and 80F. You can soak pellets in some garlic juice to stimulate his appetite.

Is it possible to keep wild caught saltwater fish as pets?

Yes it is possible, however, unless you have a lot of experience keeping saltwater fish, please do not even attempt it. Most wild caught saltwater fish will not feed when they are in an aquarium, and only a small percentage will ever learn to feed. Please leave them where they are happy and healthy and where they belong, the sea.

Hello, can you help me identify this plant please, the people at the store didn't know the species. Also is my aquarium good

Thanks for reaching out about your aquarium. Sorry not very good at botany but there should be tropical fish clubs that might help in identification. But comments about your tank. First, not sure if light penetration will be good for a plant that low in the water column. Secondly, the balanced rock formation looks tenuous, and might fall. Good luck.
