Stocking A Fish Tank

[Jv777j]

Iv had a 15 gallon fish tank for 3 months and I just wanted to know if it's overstocked. I have 4 tiger barbs, 1 balloon Molly, and a common pleco. The tigers aren't aggressive towards the other fish and I think they are full grown (they are 2 inches). So is it over stocked?

That common pleco will get a lot of attention here soon... It grows HUGE!

The only thing not suitible for that tank is the Pleco
