My tanks are all on the smaller size. My displays are all 32 or 34 gallons, so some trimming becomes necessary. I just had to cut up my favorite frogspawn, because it grew from 1 to 10 heads, was taking up an entire corner of the tank. The lower heads were getting totally shaded out and not doing well so it was time. My green slimer also got a significant trim, which also helps fill it out since multiple branches will usually sprout from each cut site. The monti caps require regular trims to stay manageable in such a tank. Seems like I accidently frag an sos every time I try to do something in the tank. I still have credit at an lfs after finally caving and pulling out an orange cap the size of a dinner plate from a biocube. I sell and trade stuff here and there. My wife convinced me to set up a frag tank and get some gear to do some shows, which were gearing up for probably early next year.
