they have a tendacy of breaking thier backs. 125g is alittle small cause of this tendacy not cause of thier size. if its ur first gar, talk to snookn21 about getting a florida gar. i highly recondmend him. 125g will work for most of a florida gars life.
shortys arnt too expensive its just finding them.
again to be honest, go with a florida. thats what i did, and i love it. u will never go back.
