So i currently have a 30 gallon fish tank . In this tank their are 2 gourami of opposite sex . 6 cherry barbs 2 clown loaches and 2 of those little pencil shaped algae eaters . The plan of this tank is that everything will remain clean and maintainence (sp) will be minimal . The idea was to go for an asian theme which so far i've succesfuly done . The loaches get the bottom , the barbs have the middle , those pencil guys the sides , and the gourami the top . However i've recently found out that apparently barbs can be fin nippers towards gourami . I've yet to see any of this or any signs of it but I'd like to be safe . Also I'd like to know if my tank is overstocked and what fish could be swapped out for the ones I currently have . Thanks.
