If they are babies, how do you know they are 3 males and 3 females?? :-?bentech said:hi!! i just bought 6 maingano (baby) to put in my 55 gallons. i ask for 1 male and 5 femeles but the guy theres make a mistake and gave me 3 males and 3 femeles :x . i have alot of rock in my tank so its almost impossible to catch 2 males and return for a exchange. So, should i let 3 males and 3 femeles together in my tank or should i take all the rock out to catch the fish and return it so i can have a 1:5 ratio ?? In the futur, i'd like them to breed. So what is the best solution ??
Maingano males and females look the same, the only way to know sex for sure is to vent them, and they need to get bigger and more mature before that can be done with any reliability. (If they're big enough to be vented, you could have done that before putting them in the tank :thumb: ) What I've found with them is that its easy to identify a dominant male, but hard to tell the difference between subdominant males and females.
Since they are in the tank, I would leave them for a while, observe them, watch for spawning, dominance, fights, stress, etc. And then only remove excess males if (when) they become a problem. If they are small babies, they could live together for about 9-12 months before a big problem occurs. Maybe pick up 6 more juvies to start with, so when all is said and done, you'll hopefully end up with at least 6, maybe 7 females, to go with 1m in a 55g.
Is there anything else in the tank or planned to go in the tank with them? I know of 1 user here a while back that posted pictures of a wild caught breeding group of mainganos that were 8m and 8f, in a single species tank. Don't remember the tank size though, may have been a 75g or a 90g.
Good luck! mainganos are feisty little fish that can go either way. :fish:
