These guys were hatched Nov. 15 of last year, so they're a little over 3 months old now. In late December I moved them into my 40 long as a growout tank, but when I needed to split up the SRT and wanted the 40 for one of them instead, I moved the midas swarm into my 8ft long 135gal, in which there were two subadult marbled fenestratus and two subadult cutteri. That was 2 weeks ago. After only one week in the big tank, I thought I was losing it because they looked noticeably larger, but it had only been a week so I figured I was imagining it. But now after only two weeks, there's no denying it - some of these have at least quadrupled their size since they made the move two weeks ago. I can't believe how much of a massive growth spurt they've had in such a short period of time.
