I have a 29 gal fresh and a 10 gal fresh, but it seems there are so many other pretty fish. I have seen many gorgeous tanks makes mine look bad but i heard it is harder to keep up those kind of tanks then fresh water tanks. I s this true...... does anyone have any advise for me. and what are the easiest to take care of .... i know my 2 are a but load of maintnance and i get up every morning hopeing to find everyone ok and looking good. i have had my tanks for 5 months and only had 3 deaths out of a good 10 fish. I have a dwarf green headed puffer in a freshwater and he seems to be doin fine.... he is my favorite......
