I'm going to be the odd man out and step up and say I wish people did not advocate this, most only show us the success of doing this, and not the great many failures.
It's just too easy to induce a split by overfeeding which is much safer.
Yeah, I guess this is faster, but most of us know the saying about rushing things in this hobby.
Sorry, just gotta shed light on possible negative outcome, hate to see people lose something they may be attached to, and I wouldn't do this in display risking fouling your tank.
Nothing wrong with being the oddman out, I often am You make a good point though. If all your trying to do is get a single BTA in your display to split into two, I agree 100%. I wouldn't hassle with cutting it. Aside from the risk of fouling your display tank, you really don't want to go tearing the thing out of your display either. Its easy to tear a foot or do other damage. This is really a setup for someone dedicated to propagating large numbers of BTA's just like setting up an individual frag tank for the same purpose.
