Mac from New Bern, NC. We have a 2 year old 45 gallon (tall) tank and haven’t kept fish since childhood. We’ve made a lot of mistakes but here’s our current pet list: 1 mystery snail, 5 serpae minors, 2 neons, 9! kuhli loaches, 1 long finned bristlenose pleco. The kuhlis got happy last year and made 6 additional loaches that we rehomed to a friend. So far we have lost 1 pleco, 4 neons and a kuhli, and had to offer 1 serpe for adoption for a bad attitude. Trying to learn and excited to join this community! We want the best for our fish. We want to change the substrate in our tank to sand and welcome any advice!
