Thanks for the nice words.
Oh...that's a great idea with the heater and I'll definitely do that. I also might turn the PH's 90 degrees so when you look at the tank head on, it looks like it doesn't take up as much space.
In the future, do I even need the HOB filter? What do you think about taking the sponge out of the filter eventually and filling the chamber up with LR rubble for extra biological filtration?
As for the worms, I'll try some DIY traps in the future. I've also read on this forum about people using pvc pipes and such. But for the time being, I might keep them in there as filter feeders and start removing them if they really take over the tank. I believe I already have at least 6 of those bad boys.
Oh yeah, do you know what baby mantis shrimp look like? I have these little shrimp-like looking things running around. Unfortunately, it would be impossible for me to take a picture of them. They are about 1/4-1/2 cm long that are sort of brownish. They have 2 long antennae. I already saw a molted exoskeleton and am worried that they are baby mantis shrimp. But maybe they are just amphipods/copepods (don't really know the difference!).
