Was doing some fragging last week and put in a glass tumbler to support a torch frag. On Monday I noticed the damsel was inside the clear tumbler which had some algea growth cover the outside slightly so i assumed it was using it as its new home. Yesterday on closer inspection I noticed the inside of the tumbler was dotted with hundreds of eggs. So ive since cleaned the tumbler to check the progress. I guess free food for a long time to come as they supposedly lay every fortnight or so.
