I’m a relatively new fish owner. I’ve owned fish for about a year now. I went on vacation for 4-ish weeks and let my friend next door take care of my 8 neon tetras. I told him how to maintain my tank and all the essential information like water changes and scheduled feeding/cleaning. Came back and my tank was a disaster. The decoration was completely moved, dust was everywhere, food was clumping up at the bottom of the tank, etc. The picture below is AFTER I cleaned up all the dust and scraped off some of the algae. I’m not sure where to go from here. Would a water change after this long kill my fish? Any help is appreciated.

If you are worried about a large water change affecting your fish then do smaller ones more regularly. Say 1 x 10% per day for a week rather than 1 x 50% change.

A gravel vac wont go amiss to clean up the waste food.

Are you able to test your water parameters?

I am able.
 
Just do the full clean. Fish will appreciate clean water. Think of a small pond getting a fresh rain storm after a drought. They'll be dancing
