How does your Pink Margin and Lineatus get along? Being such close conspecifics I was warned away from that combination as well as Lineatus / Pylei. I eventually had to remove my C. rubriventralis as he was running the Lineatus to the point that he would stay hidden and not eat.
I currently have the male Lineatus, male Hooded and a Canary wrasse. I have another male Hooded in a separate tank currently. They were both bought as juveniles with the hopes that one would be male/ female. No luck. After some serious around the tank action I grabbed the first one I could net. Both are gorgeous and coloring slightly different into their terminal stage. I believe they are from two different locales.
The Canary is to be removed as soon as it can be caught. It's appetite for shrimp (Peppermint, Cleaner, etc) is ridiculous. It also enjoys picking off snails and any other inverts. It just won't go into a trap and getting a net on it is this side of impossible.
