I actually debated on getting those or the Kendalli instead. I have mine in my tank now and they are very similar to the elongatus. I'd keep a tight lid on the tank if i were you. When i was putting the Kendalli in my tank them jumped right out of the holding bucket and into the net, no kidding. Must have been 3 feet. all i did was stand there an hold the net and they all just jumped out and into the net, it was kind of funny but made me really secure my tank lol.
