GOOD/BAD?

it looks like more than one type of macro. i think i see dollar plant. a closer shot will help determine which ones you have.

THERE APPEARS TO BE BE TWO DIFFERENT TYPES OF PLANT. IS THIS A GOOD THING? IS THE TANK HEALTHY?

some algaes are ok but others can suffocate your corals. they can be put in a fuge if it is cause for concern.

algae is not the only to tell if your tank is healthy. you must check all your water parameters. do you have test kits for ammonia, phosphates,nitrate, nitrite, calcium, etc...?
