Lion_tamer, I know you posted to not respond, but I just wanna to let you know that I am not trying to start problems with you. You seem like a really cool guy and starting problems is not the way I operate.
It just seems like you go 100% negative in a given situation whether it's about triggers, lions, etc. I wasn't telling slednecks that it was okay to put it in his tank only because I have one in my 75. The exact words I used were "I don't see a volitan being a problem in a 75 if you plan to upgrade to a bigger tank." That's an if/then clause. If you plan to upgrade, the lion is not a problem. You didn't even give him that. You went full force into saying that it would never work. The only reason it would never work is if he didn't upgrade his tank. You just assumed that he would never upgrade his tank. How many people on these boards have multiple tanks though? Come on, everyone these days has like 3 or 4 tanks. Not too many people who really get into this hobby do not wind up upgrading their tank, and some of them do so because their fish outgrow their current tank. I know I really do not have to tell you that though. You are the perfect example. You had your lion in an even smaller tank (with a harlequin tusk and yellow tang?), and your lion (back then) was larger than mine even is now.
I'm not criticizing you or anything, but why all the negativity? Conogre (among others) didn't get all negative with you when you came on here saying your volitan was in a 55 and all. And look at you, you upgraded to a nice 120.
I'm just saying all this because this is a place to come to learn. Slednecks is not learning by you telling him "no, no, no". Give him reasons. Tell him that it is a "no" unless he has definite plans financially to upgrade to a bigger tank in the next 1 or 2 years. Let him know that volitans get to be about 12"-14" pretty quickly and while a small volitan will be okay in a 75 for a year or two, eventually, a fully grown one (or one getting closer to that) will need a larger tank, like a 150. Let him know that that volitan won't be able to make his permanent home in a 75.
Saying all that, slednecks can make a better decision between say a volitan and a dwarf because he will be able to plan his future a little better. Obviously, if he has no intentions to upgrade or if he knows he will never have the room or money for a 120 or 150, he would be smart enough to not choose a volitan. Give people the benefit of the doubt...
