Thank you for the warm welcome Big Dog, mommytron, Mike and mgamer20o0! I did post a pic today of my 10g tank. Thought I did it correctly but am still learning how to navigate this site so perhaps not...will check on that pronto! Big Dog has been a blessing in disguise and has been very patient with me...I have much to learn! Mommytron, I have 4 small neon tetras (sadly one passed on today), 4 guppies (one of which is prego and I have two homes ready to welcome some of them), 1 loach. 1 cat, 1 oto, 2 small aquatic frogs and 2 mystery snails. I have a Whisper in take filter for a 10-30 gallon tank. But guess what?! I bought a 20 gallon tank today and am hoping (with help from this site OF COURSE!) to do it right this time. Get it Wednesday evening and feel like a little kid at Christmas!! It also comes with the same filter but I'm really thinking I need to invest in a hang-on power filter....what are your thoughts on that? Welcome any and all advice. Really wanted live plants and am discussing that with Big Dog but also really like my rocks in the bottom of the tank...again...any ideas or thoughts? Toss 'em my way pretty please! And mommytron, yes, I think I do need to get a different bulb. Wanna go shopping with me and show me what the heck I need?!?! Thanks again everyone...I'll get there...love this site and am so glad I happened across it.
