If you had any comprehension of the negative effects such actions of much local collecting and the impact it can have... you'd remove the attitude (which is pretty digusting) and possibly understand the reason for someone writing in a way that may not be so nice out of a passionate heart for the animals. Releasing the fish after the fact cannot happen. Just another senario of know before you buy/take. What if this fish were protected? Then what?
It's not like asking about a common fish found in a LFS... it is asking about a fish native to a specific area, which most times if not almost all times without the proper system will die. I've known people that have kept tanks with local animals, not the issue here. The issue is this person took something, didn't know what it was and decided to put it in their tank.
What's done is done you say... fine... information was offered on what the fish was so the original poster here can find the information about the fish to hopefully have success in keeping it. Though if noone warns of the reasons why you shouldn't just take things blindly from the waterways, what will happen next time?
If you take notice I didn't need to use profanity once in my reply to you.
