5 silver dollars in a 35g is not a good idea, where ever you got that information from I dont know but that definately should not be done. Jmo but fish like silver dollars with their need for lots of swimming space will need a tank of at least 75g or more(which you have), you have to remember they do better in shoals. The clown loachs are definately a no no, and if you think that they are , I would check you sources again, they have the potential to grow to 12 inches in the appropriate enviroment, so provide the approprate enviroment or dont get them, hoping they will only grow to 6 inches is cruel.
Other than that I think you are fine.
