control your lighting and feeding.
Lighting: that's the reason why a few of us recommended to start off with 6hrs of lighting for some time to observe the growth of the plants as well as any algae bloom. with your current plant list, i suspect algae is going to grow because your plants are outnumbered. but as you increase your plant list, the chance of algae growth should be reduced.
Feeding: when feeding your fish, make sure you don't overfeed them. the excess food will decompose into a number of chemicals that are ideal for algae growth. feed your fish however much they will eat in 2-3 minutes.
ps. i wouldn't worry about algae that much for now because a healthy balanced tank always have some algae in it. when you see algae growing, you know right off the bat something is going well (ie there's enough nutrient and lighting). when algae becomes a nuisance, introduce algae eating species. nerite snails are a good option. otos are excellent for small tank like yours.
