Get Your MonsterFishKeepers Cap

Welcome to MonsterFishKeepers.com

The members of this forum have come together to share our knowledge and experiences of fish keeping. We want to answer your questions, offer advice and fill the galleries with pictures of the fish we have all grown to love.

We are a unique community of Fish Keepers who seriously take our hobby to extremes and the NEXT level. The majority of our fish collections include RARE & EXOTIC Species of all sizes, BIG FISH with BIG APPETITES and BIG TANKS. It's not easy for most people or other "regular" fish keepers to understand why we maintain this type of collection and spare no expense on this fascinating hobby.

Hopefully, through this site and discussion forums we can encourage the next generation of Monster Fish Keepers to have the same passion and love we have for the hobby and our Monster Fish .

      I have a Freddy and an RTM. They are both 3-4 inches. Any guesses on gender?

      I’m going with male on the Freddy and female on the mota. Are they sharing the same tank? If so the mota MIGHT be a recessive male

      With either species the profile will be higher in males, and more torpedo shaped in females. Here are some examples.

      closer up, note the smaller sporting

      now compare a female
      [​IMG]
      note the lack of smaller spots on the female but the few large ones

      These traits (especially the high profile) hold true on most all the Parachromis like predatory species and their cousins

      now a female
