We have the 2.5 Aqueon minibow. It is a nice and not noisy..however, it is more 2 gallons than 2.5 after decorations are added... it also scratches pretty easily. ( it could be that I am not used to acrylic tanks though)
I have only had it for a few weeks and I have already accidentally scratched it pretty badly.
I do like the tank though.
Walmart has a 5 gallon tank with hoodlight and filter for 25.00 dollars, it might be something to look into.
It is actually a pretty small tank and doesn't take up much more room then the 2.5 gallon.
I have this one and I love it.
