Shweet pike yaz got there bro!! Lugubris pikes totally rock. Very nice pick up there. Shes gorgeous. My xingu I female really colored up once she hit 10"...got the white outline on the dorsal fin...and BRIGHT red stomach. You got a mate for her? She is rather large...lol...if you do i hope they pair up aight. As for the spot in the dorsla fin...that isn't so much a fact for Lugubris pikes as it is for Saxatilis pikes. In Lugubris pikes, such as Crenicichla marmorata, lenticulata, xingu's, and the tapajos just to name a few, both the male and the female have the caudual fin spot. Also, Lugubris females are generally are smaller, and in my opinion more colorful. They get the bright red stomachs and in most species get white lining on the dorsal fin. Anyway, drop your pH to about 6.5 if it isn't there already and give her a cooler water change...she'll color up NICELY. Cheers,
Jer
