You already have 25 bodies in a 20g tank and you're thinking of getting some
more? Do the fish even have room to swim with the plants in there?
What about cycling? Did you use filter media or water from a cycled tank?
What kind of filtering do you have anyway? Plants can take some load off of
bio-filters but you're going to have a hard time squeezing enough plants in
a 20g to take care of all the waste from 25 fish. I suspect the algae is
responding to the available nutrients that the other plants and bio-filter
can't take fast enough.

Too many nutrients seems pretty likely.

I see hillstream loaches mentioned here from time to time. Do these really
eat algae or is this just some rumour/assumption?
