Almost 48 hours with no leaks! Got the rest of my substrate in today, also put a few more fish in from the 80 gallon. I'm measuring each fish I put in the 400 to monitor growth rates. Also got my top all in place, I'll take pictures of it later, just did glass on the front half and wood doors with handles on the back half. Simple, cheap and functional!

Sailfin Pleco - 6.5" (Purchased at 1.5")

Smallest Jaguar Cichlid - 6.75" (Purchased at 1.25")

Tiger Oscar - 5.5" (Received at 5.5")

Yoyo Loach - 2.75" - (Purchased at 2") - He's lasted 6 months with all my big cichlids, see how long he'll make it in the big tank!

Clown Knife - 14.5" - (Purchased at 14.5")
That's what's in the 400 now, will be adding the rest soon.
A question for anyone with a large tank. Everything I read about large tanks said it was usually an issue keeping the tank cool, rather than warm, I have mine in the basement with the top on and my FX5 circulating and the water won't stay about 70 degrees, my fish obviously aren't going to thrive at that temperature, I would like 74-78 degrees. So do I insulate the tank? Or heat it or what?
