Hi all and thanks for the info...yeah thats what they were doing and how they look like.
Well we managed to stabilized the 7 of them... chowing down on and decimating my lateralis population :\
Sadly we lost one last night...and is worried for the other two who are very stressed out and looks like they are quite worned out...
The importer kept them in a tank with cocopeat substrate and i guess that sort of like itch them out as they were covered with it...
Hope the rest of the 7 will get better and put on more weight...
