i have seven blue dolphins and five frontosas in a 125 gallon(6 ft).i have a dominant male in each group and the rest are still unsexable,all are young fish.if you go by the various inches rules (which i normally dont)that equals 116+ inches i have never owned any of these fish as adults so im not sure what to expect. i know what all the books and websites say.but i would really like to know what the rest of you think.right now the sizes are blue dolphins-1 four inch male, 2-three inch,4-two inch. frontosas- 1 -four inch male, 2-three inch, 2-two inch equalling(sp?) 32 inches.i dont wish to keep either species in any smaller of a group.in about 1 years time i will have a pond built in my basement between 500 and 1200 gallons and they may go in there anyway.obviously fish as beautiful as these i would much rather have in an aquarium so all quests can see the fish up close but i care about my fish more,especially flipper(blue dolphin male) and franky the mafia fish(frontosa male).oh and i say they're males because they were purchased at the same time as the three inchers from both groups and grew twice as fast and both have rather large humps for there size but most women i meet say im an idiot so i could be wrong.
