Amano shrimp - males remain quite small 2-3cm maybe, females get large & tend to become fish food fanatics in hiding so not that useful as algae crew once fish are added to a scape
Tiger shrimp are amazing, red nose shrimp are the most efficient at BBA (but can be short lived depending on species & source)
Try to purchase shrimps in groups of 10-12, they really do prefer a decent “shoal” of their own
Various snails especially Clithon species are advocated for BBA - note any consumption of BBA is pretty much at the early stages (or clean up after you’ve done a chemical kill) (note Clithon species remain quite small so a group of 10 would be my starting point)
Before fish, take advantage & run the tank cooler, eg 20-22C (shrimp will be happy as well)
If you see visible algae, increase maintenance ie water changes & physical removal
Frequent water changes (especially daily) are very useful at limiting algae
Before livestock, you can also also run high CO2, CO2 24/7 (I usually increase surface agitation at night) etc
As plants & aquarium microflora establish, reduce water change frequency - use this as your guide rather than any “set” time, if you reduce wc frequency & observe visible algae or tank odour changes, increase water change frequency again for a week or two
Refill with cooler water - plants seem to appreciate this
