I have had a juvenile Linni for about 2 months. Not sure yet if it is male or female. It is in a 125 gallon with 11 other assorted haps, peacocks and mbuna. They all get along great. I provide plenty of rock for them to explore and or hide. My Linni started acting differently yesterday. It does not swim around much. Shows limited interest in food. If it does pick up a pellet that has made it to the bottom, it sometimes spits it out. There are no visible signs of anything, i.e. ich, fin rot etc. It almost seems to be acting like a holding female, but like I said, it will pick up a pellet now and then. I don't think it is possible that it is holding since I have never witnessed any breeding behavior andI only have one Linni. I suppose anything is possible when it comes to cross breeding, just not sure with a Linni. I have the following livestock. Linni, OB Peacock, VC 10, Venustus male, Red Fin Borleyi male, Yello Lab, Red Zebra, Yello Tail Acei, Demasoni, Williamsi Blue Lips, Red Top Trewavase, and a common Jewel. I know, the Jewel is an odd fish for this tank, but I have one and it is pretty cool. I stay on top of my tank, weekly water changes, frequent testing etc. Ammonia at 0, Nitrites at 0, and I don't let Nitrates go above 40. Any ideas on what might be going on with my Linni? It would be very hard to catch him and isolate him without tearing down all my rocks, plus like I said, it is a 125. Lots of room for it to escape my net. Any input would be appreciated. Thanks.
