Awesome setup! I see some beautiful fish in there, what all is stocked in your tank?
You must have some really good mates to help you with all of that and to look after your fish when you are away.
Not sure how I missed this until now.
Nice Setup! Good on you going to the effort for insulation etc, I know of others who wing it and loose expensive fish every summer, crazy.
I'm also in Perth, curious where you had the 10x3x2.5 setup built? I've recently just upgraded to a 6x2x3, but already planning the next step which I'm wanting around the size you have so I can expand and keep rays with my other South Americans.
Keep up the good work and keep the posts and pics coming.
Cheers
