I was at petsmart today and there was this family with their little boy getting fish. The little boy wanted some bala sharks. I asked them what size tank they had (8 gallons) and told them that balas get to be over a foot long and need to be in a large group. The pet store people said that they could have up to 8 in that size tank! I ended up helping them get a couple platies instead. I know pet stores dont educate their employees but 8 sharks in an 8 gallon?! I mean the price tag even had a minimum tank size of 55g which is still too small but better than 8! It's so sad to see all of these people misinformed and fish sent of to live their lives in misery
