You should. They don't seem to grow too fast and are pretty visible and active in my tank, for the most part. The big guy is much more elusive than the little one since I moved them into a larger tank with a bigger log that he can hide in. The little one is almost always out and shoots up to the surface when I drop in some bloodworms. Definitely wise buys for $12 and $6.LittleBigAl3;2679748; said:this wants me to go out and buy one...
