I lost four cichla orinoco six seconds after putting them in my tank, because I overestimated their size. I had been looking for those cichlas for six months. The compatibility was perfect, my eagerness was not.Well, mistake happen all the time! In fact, I just made a mistake (or under estimate) my Tess. Moray power. I introduced a big Majestic Angelfish to my moray tank, I thought it too big for my Moray to eat and before I release the angel into my tank I fed my moray 4 medium size Octopus (6 inches size) to avoid its looking the new tank mate as food. This monster Moray gulfed down the expensive meal less than 30 seconds!
*Note:
Usually moray won't able to catch fast swimming healthy fish but my moray do it with flashy speed attack and got the angel. O.O I'm speechless!
Mistakes do happen, we can only try our best to make as few as possible.
