I am setting up a 2.5 gallon nano with LR/LS I was going to convert the
smallest size Penguin Bio wheel filter to a mechanical filter/heater
chamber. I can then still leave the bio wheel in place and have extra
wet/dry bio filtration. Does this sound possible? How about adding a single
small Goby or clown to this tank? would it be possible or should I stick to
a Sexy shrimp or two?

Thanx,
Matt
