They were about 3 inch swordtails and EBA about 4 inch and 3 inch they have not paired off so probably same sex I added the swordtails after moving tank around thinking that would help they did not like them from the start had to give up the idea after two were killed

It is unusual but I have a large male bristle nose who it is rare to see on the glass had him for six years now and he prefers working the bottom for shrimp pellets fights the other bottom feeders for them
I keep them in a 20H and they seemed fine when I first started after having them in a 55 and 150 they do so much better and grow bigger. They are a great fish not everybody has a bigger tank if I only a had 29 it would not stop me from having them as a centerpiece fish.

Me to I even had a large pair of angelfish in the tank thinking they had me covered after they had eaten all the guppies my wife has not forgiven me for what happened to the angels needless to say they ate few before needing to leave the tank.
