I just wanted to say hi to everyone, i'm fairly new aquarium keeper i've grown up watching my dad with his aquariums and decided to start my own and i've found this app really helpful so far..Thanks for the warm welcome everyone. Also i started my 10 gallon fish tank with 2 feeder goldfish not sure the correct term so if someone could inform me..also i have a female red craw crab in there as well (she has a way to get up the air/land) but any advice would be great!
