This is a gorgeous tank, don’t get me wrong but he just lets his filter do the cleaning and just adds water. He has fancy guppies and bloody mary shrimp in it, but he also suggested to me NOT to clean my tank do all the work. At this point I don’t even know anymore cause even my parents (who know nothing about fish or fish care) are like “clean my tank once a month”. What should I even do? I only have a betta fish (who is in a hospital tank atm) but he gave me quite a lot of shrimp for my 5 gal tank…
