I like the aggresive tanks. There seem to more activity in my aggressive tank than my passive. I have a 125 with a 6" niger , 4.5" butter hamlet , 6" fuzzy dwarf lion and a 24" snowflake . Peole who see the tank tell me it looks empty , but the trigger is always cruising. He checks the nooks and crannies of the rock and he will even burrow under them some times, till the snowfalke chases him out
The hamlet cruises the top and mid section of tank and the lion ... well he is a lionfish, he just likes to lounge around till there is a piece food to chase across the tank that is getting blown by the power head. The snowflake is the baby I feed him hunks of shrimp or clam on a screwer. Though the niger or the hamlet sometimes ends up with it regardless
But there always movement ,always fun to sit back and loose myself looking at them swimming around. Though that happens on my passive tank as well. Isn't that why i set them up in the first place ?? heheh
