'The Un-Amazon' tetra haven

[BlueAbyss]

Yup, no artificial anything in this tank.

EDIT: Hmm, I'll bet you're thinking about the sun heating the tank... I'm home during the day and have observed around a 2.5 degree Celsius rise in the temperature over an 8 hour photoperiod (currently, this will change as summer comes closer), with around 6 hours of direct sun. I will need to get something in place to deal with this... so I'm building my own mini-chiller. Should be much cheaper than those Coolworks setups, though I could just save some cash up and add one of those to the HOB filter. I'll document the build when I do it for the benefit of others.
