I have a BTA and a pair of clarkiis available for free to any supporting member. The BTA was graciously provided by @Newjack to specifically catch this pair of clarkiis. Thanks @Newjack! I removed my original rainbow BTA as it started walking towards my more expensive acros (got nervous) and the female clarkii was none too happy and started annoying other corals in search of a new home. With a BTA in the tank, she is happy as a peach and leaves corals alone. These clarkiis will behave well together in a larger tank (I have had both clarkiis for 4-5 months without an issue in my reefer 250), however, the female doesn't like him sleeping with her in the nem at night as I found out after I caught them and put all three in a small fish "jail". As a result, the male clarkii is a little beat up (fins frayed) and will need some r&r to be nursed back to health. He was very healthy before this "lovers quarrel.". These clarkiis even coexisted with a bonded pair of occellaris clownfish and aside from a "meet and greet session" the first day, everyone has been model citizens and they pretty much ignored each other. BTA is 8" tip to tip and clarkiis are around 1.5-2". Anyone taking up this offer must take nem and both clarkiis! I am located in Castro Valley.
