can anybody out there give me a good website that shows pictures and gives good info on good and bad life from LR. ive been viewing alot of life in the past 2 weeks and just wanted to get some basic info on most of them. i have a bristle worm problem already and i was woundering what the best way would be to keep their population on the small side. i heard of an arrow crab, but is this the best way?? also is a trap as easy to use as it looks?? i also have some shrimp looking animals that move extremely fast. they look like J but i dont believe they are a mantis shrimp. there is a s*** ton of them, and im not sure if its that big a deal or not. neways im sorry this is long winded but any info on this would be great. thanks
