Hey everyone, sorry it's been long since I've updated! So out of the trio, I have one very large and fat one left! I have found that raising multiple Lennardi are quite similar to the multiple femininus that I've raised before.
They all get along peacefully at first, but one becomes dominant and territorial and bullies the rest until they just hide in the sand and never come out again. I think my tank may not be long enough at 5.5'. I know of people who have successfully raised multiple femininus long term in longer 8' tanks.
Anyway, I was planning to clean my tank today so I'll post pics/videos after.
Happy New Year!
