wait wait there- would you rather be a football widow??
well be assured there that the other side of this coin also exists. there are some female caudate obsessors-like pin pin and jenni and i (although i am single and have over 50 filled tanks and many more temp containers and have my animals in 2 different locations-so im a little out of the loop). if a man is to get obsessively into herps it is better -in my opinion- to do these, they arent expensive and macho -like snakes and lizards-so he probably wont get into obsessive '1 upping-ness'. one thing to note about these animals is they are very soothing to watch-and more interactive than fish, lizards, snakes, rabbits etc...they are unique in their character in that they are not by nature 'agressive' (ok maybe a hellbender if its threatened-but a human approaching them has no fear of them lunging out and biting-like lizards, snakes and rats-there is no need to 'tame' them) humans are seen as 'food dispensers' not threats. (i have been bitten only once and it was on mistake since he was blind in that eye and i handed him food) on just a purely pragmatic look at them -they reduce stress and cost less than fancy salt water fish set ups-so your guy should be a fairly mellow guy-and he probably doesnt spend alot of cash on going out and partying-right? (i know im more interested in my guys-and i have much much more than most people-than drink, drugs or partying (my animals cost as much as a drug habit- a LIGHT drug habit-but are much more fulfilling)
my one selling point to other people i meet about the animals is that 'it is like gardening but with a twist'. it is a very nurturing hobby-my previous hobby was collecting breyer model horses -i had over 500 of them-so i have replaced one obsessive hobby with another but this hobby is at least a constant learning experience that enriches my life-not like my old one that was just 'treasure hunting and hoarding'-the upside is that i am always learning something(which is my biggest hobby -learning) and i can occasionally subsidise a little of the hobby by selling CB offspring. on top of this i have now returned to school to complete 2 degrees to further my interest in these animals and the environment. the fact that you BF is interested in them tells alot of his character-it is a form of stress relief - do you fear it is a form of escapism?
one of the draws to this hobby is to create small worlds and to feel all is well when the animals are healthy, interactive and will reproduce. the upside of these guys is they are restricted to cages/tanks and thus the house wont smell (although my sister complains of the algae smell -its still better than a house filled with dogs, cats or snakes). you may want to address the issue with him that you fear it is a form of escapism - but the hobby itself then isnt to blame. i myself find that encouraging others to see my world often drags them in (and herping hikes are ideal interactive dates to me)my nieces, coworkers, coworkers kids and even strangers are facinated by these creatures (even pipa pipas and caecilians) maybe perhaps because enthusiasm is contageous -but again its got alot to say about character.
