Thanks!!
As for the tank itself, since the last update I've lost bout half the silver tips possibly to predation (though not sure who? Uaru? Flagtail? Heckelii might be big enough?) and going over the overflow and not being rescued in time. The Lemons seemed to "learn" to avoid it, but the silver tips didn't. Seems how the Amazon theme was blown I added a school of scissor tails and they're doing great. Better size for a tank like that too.
Everything else, the filter and lighting etc, just keeps on ticking over and I'm sure it would continue to do so for many years still.
