The heater is from hydor; theo heater. It is indeed a 50 W.
The filter came with the tank, It's a Topfin
As you can see I have it running vertically, but even when I place the thermometer right next to it, it reads much much less that the knob is set to. The light going off for awhile then back on indicates it thinks its maintaining whatever temp its set for, which is not what is indicated on the knob.
Well this is my setup
I'll be placing those plants on the left side of the tank to balance the setting out.
Right above the rock cave looking thing is where the current is worst. I need to diffuse the flow there badly 'cause he was pushed down and looked like he was gonna hit the rock roof. He swims against the current now over on the left, I figure it's his workout. Since he is getting all this exercise... I fed him 2 extra pellets yesterday. I can hear him munch on them, It's pretty cute.
The wooden piece I bought is fantastic. I find him sleeping in a nook when I get home in the morning.
Speaking of feeding, he spat out his second pellet a bit ago as I was feeding him. I decided to try a couple of flakes but he spat them out too. I've read here about alternating food so they don't get bored, but Darius (my beta) doesn't seem to want what I have. So I figure he is either not hungry, or he is being picky. There is a pet store that has all sorts of things he would like, but I'll research here and find out how often I will treat him. Im just mentioning this, kind of thinking out loud so you all know where I'm at.
