Got these little guys a while ago. Had them very slowly growing out in a 50g tank. They had started getting pretty nippy of late and while doing water changes today I noticed one was dead. I had 8 and am now down to 7. I moved them to a 90g that is stuffed with rock, fake plants and pots so hopefully there will be no more casualties. They are now between 2-3.5". They were about 0.75" when I got them. They are one mean little fish, they are just now really starting to show the honeycomb pattern.
