Another A. modestus!!Sweet! Did you just get it ? I have a 4.5 inch full grown one in a 20 long and it is a great fish! I will sometimes feed mine small crabs and it will pick them apart and leave only the halfshell. If he is in a bad mood, which is most of the time, it will spit a very short distance at your hand or try and bite fingers when you feed it. Very mean for such a little guy! IT really is more of a fresh water trigger!!!
