Because my 46 gallon is delayed we went out to get a 10 gallon tank set with Whisper 10 filter and a 20" flurescent hood with 15 watt.
At the moment we got 9 tetra ( 3 phanton, 3 red eye, 3 longfin serpae).
(Even they will all move to the big tank in a couple weeks, would you consider it crowded or does it have a little more space for a few more ? The 10 gallon will later be used as a QT
My main question however:
When I turn the light on, all Tetra move to the ground and swim around there. Do I turn off the lights they move all over the tank.
At the moment I got gray gravel ("pure water pebbles") and 2 rainbox stones with holes which are used for swim throughs.
