42 gal stoking need some ideas.
 

KO so I have a 42 gal and I don't know what to put in it.

The stoking is one 36cm common pleco and 4 silver dollars.

The fish must not be to large(not over 35cm) and not to small(not under 10cm)

The tank is 80cm long, 40cm high and 50cm wide.

PH6.8

GH 6

Few gouramis? Maybe a few angelfish but it might be slightly small, you have soft water so there are a ton of tetras you could get that would shoal. Could get some kuhli loaches, hatchetfish lots of options

I have a gourami tank.

I have a angel tank.

Hatchets are out of the tank.(not a very good lid)

I like the bigger tetras like the diamond, bleeding hart.

Make a nice soft water tetra tank then, get your diamonds and bleeding hearts and maybe some small ones like cochu and black neon tetra

That is a big pleco for that size tank. Between that and the silver dollars, which will also outgrow the tank, it's difficult to make any suggestions.

The SD are out.

I think I'll use the tank as a grow out for angel and convict fry.
