I gutted the left side of the tank the same as I did a month ago with the right side. The entire land mass is now elevated over the water area creating a cave underneath for the fish to swim and hide. Because of that now at least 95% of the bottom area of the tank is available to the fish. The only place the fish can't swim is where the rock touchs the bottom- everything else is elevated and open to the fish.
Another Change: I have recreated a thunderstorm inside the tank. Between 10-10:30 pm every night a thunder and lightning track plays which I have hooked up to a lightning controller(from firefly). The main lights turn off, moon lights come on and then two special lights hooked up to the lightning controller flash during the lightning strikes on the CD. The misting system is also timed to come on and off during the "storm" period.
I will probably have to eventually set-up a you-tube video to show the effects. I thought the entire"storm"idea would freak out the animals-especially the discus but on the contrary. Nothing seems to be effected by it. None of the animals have been spooked.
Fish update:
The discus are pairing off and spawning-but they are eating the eggs-oh well.
The stingray is getting massive. The discus do not seem to be fazed by the activities of the stingray. In fact the stingray can swim over the discus and even "top" them with out so much as a reaction.
Frogs have been put into the system. They use 100% of the space. I was very hesitant to place them inside-thinking it was a little to wild and dangerous -especially with all the water.
So far the water hasn't effected them at all. The two seperate islands aren't actually connected. This means the left and right side land masses aren't joined. But the frogs have no problem getting back and forth. One frog in particular has made a home on top of the main waterfall as well.
I have had one frog escape and perish.
The natural food sources also seem to be a real treat. I have 4 different areas that I stick whole bananas and other fruit to attract and draw in fruit flies. These areas seem to be gathering areas for the frogs.
I am also raising fruit flies so I can supply "enhanced-dusted" food.
