ok what can go with a pair of julidochromis reganijulis yes
altos no
ok well i already have a pair...getter to get a colony then a pair for julies. you might get away with a single alto though
no the julidochromis what can go with them...altos are slow growers but would be better off in a bigger tank...i think the julis get kind of aggressive when they spawn.....not sure what else to go with the altos...id just get a small synodontis or 2 to go with the altos
