Multies running the tank

December 8, 2009

Of the 11 multies I received over the weekend, 3 camps have formed in my 20g long.  About 5 or so fish have congregated to the front right corner of the tank.  This group is composed of maybe a single male, a female and some juvies.  Another group of about 3 have staked out territory in the sea shell bed I laid out on the left side of the tank.  The remaining 3 or so juvies just sort of hang out on their own in various nooks and crannies, but kept apart from the 2 groups formed.

The 3 caudos are having a harder time establishing their territory. This is surprising as they are bigger than the multies, but I guess there is strength in numbers. One caudo is pinned to the upper left hand corner of the tank, I fear for his survival as he looked sickly compared to the other 2 caudos. 

One of the caudos is trying to slowly weave his way into the right side of the tank that has a mixture of rock, plants and driftwood. However, ever time he nears, the colony of 5 multies work together to push him back. It’s quite amusing as sometime he will be able to hover in their territory for a bit before they notice him there.

The other caudo has taken refuge in a small cave like structure near the center of the tank. Whenever he gets near the shell bed, he gets chased away by the multi trio there.  He will either go to the top of the tank near the pinned caudo, or he will retreat back to the safety of his cave.

I really thought the caudos would take over the tank and leave the poor multies hiding in shells most of the time, however the opposite has proven to be true. My multies are out and about swimming all over the place. I was afraid they would be hidden most of the time, but perhaps the abundance of shells, plants, rocks and driftwood has made them comfortable and secure.
