I think they're both cool, just depends on what you like. I enjoy all the little creatures interacting in a SW tank, and on some of the bigger tanks SW fish have great personality and behavior. Freshwater is my personal choice, I like my big aggressive CA cichlids. Also, I enjoy filling my tank with tap water and not having to worry as much about water chemistry. Planted tanks are another really cool aspect of freshwater, if you look at some of the Amano style stuff it's just unbelievable.
i like the way you think, you acknowledge both types of fish for what they are and not for what they aren't. should i get a school of 4-5 balas just to enjoy my tank until i can afford to go salt which would be a few months to a year or should i wait and sell my current stock when i can afford to go SW, or should i get a school of balas and keep my current tank running fresh and get a second smaller 10-20 gallon aquarium in a few months on my birthday in november and turn that into salt? what do you think is the best choice? and beautiful beautiful beautiful {there had to say it 3 times} tank.
One of my issues with a lot of SW tanks is it's harder to disguise a lot of equipment and stuff. A lot of Sw tanks very obviously look like fish tanks with all the equipment hanging out. I've managed to avoid a lot of that with my 125...
Minus the canister output which I'm working on disguising next. I'd like to see some of the techniques I used in the 125 used in a SW tank (background and stuff), would be awesome.
