If I didn't see it wouldn't believe it, my 12 inch Frontosa Moba a.k.a ( Blue) which is my alpha shares his cave with my male comp. and a syno cat. This relationship seemed to be working well as the comp acted as the watch dog and kept all others out and the syno cat would keep the cave clean. Well I was watching the fish and noticed a disturbance in the cave, Blue and the comp were fighting, which was funny because at 4 inches the comp can move faster than the Front. It apppeared Blue was trying to evict the comp from his cave for some reason. Then it happened Blue finally caught the comp by the tail, half way up his body. I was saying to my self this is not going to end well, then Blue came out of the cave with the comp in his mouth, swam about 2 feet and let him go. After that the comp got the hint and decided to bother his female. They have since made up and the comp is guarding the cave again. Would have loved to get that on camera.
