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 feed my rtc with arapaima XDD... i really hate my rtc, every fish that is near in front of him, he would eat it, no matter how big it is. "I moved my arapaima to a bigger tank 150 x 50 x 70, that tank is full of predator fish (community fish tank), my arapaima was 12 cm long, because i was thinking that it would be better if i moved him to that tank (friends you know?), then I leave it for a hour, when i came back, I was looking for the arapaima, and i was asking where is he???, and when I look up to the RTC's stomach... –_– THEN I WAS LIKE RAMPAGING, AND RAPE THAT RTC AND HIT IT WITH A HAMMER, IM NOT GONNA STOP UNTIL HE THROW OUT THE ARAPAIMA FROM THE RTC'S STOMACH, I REALLY HATE IT, AND I NAMED THE RTC, DEVIL CATFISH. I REALLY LOVED THAT ARAPAIMA, I raised the arapaima when he was just a little fry, I cried dude.

      It matters how big RTC tank mate is. If it doesn't fit in its mouth neither from the front, nor from the back end, it is generally safe. For instance, adult niger catfish, pacu, barramundi, distichodus sexfasciatum, TSN, jau catfish, arapaima have so far been safe with my 10 RTC, the biggest of which are 3'-3.5'.

      Silver arowana at 2.5' - not so much. When they hit their head during mating season fights and become discombobulated, the RTCs try to swallow them. Although they have never succeeded yet, they produce enough stress and strip enough scales from the tail end that the arowana need a rehab. Sometimes they don't make it from the rehab. So I don't keep aros with RTC any longer.

      @thebiggerthebetter@thebiggerthebetter would you say it would be possible to keep Malapterurus electricus with an RTC? mainly wondering if the defensive shock would be enough to deter the RTC from trying to eat it, and on the other hand would that shock be dangerous to the RTC?

      It'd be a gamble. TBH, a cruel gamble to both fish, IMHO. Sizes matter, as e-cat's max voltage is a function of the body size, which is a battery. The bigger the body, the bigger the battery, the higher the voltage discharge. IIRC, only the biggest 3-footers can produce 350 Volt.

      Perhaps crudely, we may extrapolate and say that 1-footer is able to produce only 100 V, 2-footer 200 V, etc.

      The only consistent reports I have seen of e-cat's tank mates being safe are with synodontis catfish of various species.
