I was looking to purchase a Lima Shovelnose and was sold a Tiger Shovel Nose. It was only $19.99, good deal? Should I keep it or return it? I will be able to get a 250Gal tank in about 2 years is that long enough to keep in the 90? Its in a 90G with a Gar, spec and a lmb, the TSN is about 4 in - 5 in...with a gut full of rosey's
