We have a 100 litre tank with at the moment 4 female betta's....soon to be 6 when i add the other 2, but my partner has seen some beautiful killifish & would like some. Our aquarium only sells them in pairs as male & female & i wondered whether they'd be compatible with female betta's????
i'm kinding hoping they are as i seem to have taken over the house with my betta's

& i'd like to let him have his own fish which he chooses & likes. LOL!
