dood your golden...
i started out with 10 bluelegs, like 20 snails, im down to 3 hermits, and like 15 snails a year later...
they will ballance out as the tank demands,
but you can mix them, and they are very fun 2 watch.
i have mainly astrea's, torchus, 1 margareta (soki, from the first batch over a year ago) nanassus's and a bumble bee snail who shows up every once and a while.
most of the times, the hermits only get the "derail" snails, (who flip over)
this one time i watched a hermit try to get a tourchus he was on his shell, and you could see him trying to pry him over, the tourch's did there twist up move, throwing the hermit off his shell, and all the way 2 the sand.... It was funny
