Hi! I used to have an aquarium as a teenager and, after a number of years, am now returning to the hobby. I've had a small 2.5 gallon freshwater tank with 6 neon tetras for 6 months and will be moving them to a 20 gallon tank with some new friends soon. I hope to get some help with tank levelling to start. This looks like a great forum and I'm looking forward to being able to chat 'fish' with all of you!
