After a week:
The chainlink and the zebra settled in nicely and eat like a champ while the snowflake seem stressed out with 2 bigger eels, the chainlink is very expressive eater behave and its even stole the piece of food from zebra mouth, its over excited and swim over everywhere when it smell food in the tank LOL (same like my Tess). So I decided to trade the chainlink and snowflake for another zebra
There is territorial expression from the old zebra with the new zebra. Yes, they are fight a bit and there is some warning bites from the old zebra. Soon the new zebra learned not wander into the old zebra cave and everyone peace out
There are 2 sets of PVC pipe caves under the rocks so there won't be anymore problem when the new one claim the other set of cave for itself. I was looking to get a few fire shrimps for tank mate but somehow all LFS OUT of STOCK all Fire Shrimp
, it's a risk move because my eels are small and might eat the shrimp, I knew when the eels big enough they will leave those cleaner shrimps alone like my Tesselata.
