Buying fish for the aquarium

Today, after having lunch, we decided that the aquarium at home has been empty for too long and we needed to put some fish into it.
There was an aquarium shop along Jalan Ulu Klang, as we come from the MRR-2 Road from Maluri.
Dropped by an chose one of the cheapest and easiest to care for fish. They call it 'ikan puyu', and it is a river fish.
According to the shop owner this particular fish was easy to take care and they don't die easily. Exactly what I had in mind, since from our past experiences, all fish will die off within a month or so and we had to replace them everytime during Deepavali!
Each cost us only RM2.00, compared to other breeds which ranged from RM 20.00 a pair to even RM 80.00 a pair. LA was very excited to see the fish being let into the aquarium.
