Hi. Just want to ask for you guys opinion. My friend just bought an 40 cm x 40 cm x 40 cm aquarium. I think he is using some kind of chinese brand filter (boyu) that is equivalent to eheim mini in term of the filtration rate. He is doing some aquascaping inside the tank with 20 cherry shrimp, 10 neon tetra, 10 ember tetra, 5 galaxy rasbora, and 5 scarlet badis. Should i tell him that he is kinda pushing it or is the tank population just fine? Thanks and sorry for my messy english
