I recently purchased a new 120 gallon for my loaches so I thought I'd share the specifics and photos with the community here. Feedback, constructive criticism, etc. is always appreciated.

The old 55 gallon tank is here:

The pleco and loaches were growing a little too big for that tank so it was time for an upgrade.
Equipment:
120 Gallon Tank
Filster XP3
Aquaclear 50 Powerhead w/ Quick Filter (back left corner)
Hydor Koriala 1 (back right corner)
Hydor Koriala 3 (front right corner)
300 Watt Heater
Substrate - Eco-Complete w/ gravel on top
Fish:
7 Chromobotia macracanthus (2-3 inches)
4 Botia almorhae
1 Crossocheilus siamensis (he thinks he's a loach)
1 Plecostomus
...and a huge black PVC tunnel system for them to hide and play.
Future Direction:
The old tank had quite a few plants and they held up well against the loaches - but unfortunately my high-wattage light ended up breaking so most of them didn't last. On the priority board for future purchases are a sump to replace the filter and a new lighting ballast to add some colorful green to the tank. Thanks for looking!
