once again, based on my research ( i have yet to own one mandarin!) all people suggest that you should off your pump when feeding the mandarin.. since they are slow feeders.. so the pods/frozen food will not fly around.. can use your balloon stick to train it to recognize that the stick means food too.
I'm plannign to go to pasir ris this friday. Can anyone tell me where is this ah beng's shop, and what other shops in pasir ris I should visit for coral livestock?
