i don't want to say for sure... but be prepared to move fronts because of socofoli... fronts are extremely timid... and if the socofoli stress them they could get sick and perish..fronts at this size are really a risk.. so watch careful.. make sure they are eating etc.. because they cannot and won't compete for food against the socofoli if they feel threatened.. the fronts should eat from the substrate.. and not from top... they suck in air easily... hope they do well for you..they are adorable..
