I just wanted to say 'hello' as a total noob and say that this is the nicest fish forum! I posted messages in some other forums and it got downright catty with members fighting and arguing back and forth in their posts. Sheesh! This forum has been so kind and supportive. I am very happy to have found you! Thanks for all the help so far. I am setting up my first tank as a birthday present for my daughter. I'm sure I'll have many more questions in the coming weeks and months as I get that tank more established and start to work on a second tank - a betta for my office. So excited about tank #2 already! So thank you all for being AWESOME and helping me get a successful start in this (super duper expensive) hobby.
