This morning, I went to Langat Aquatech Sdn. Bhd. to purchase tilapia fingerlings. The price are RM0.25 for one 2" fingerling and RM0.50 for 4" ones. They only sell a minimum of 100 fries for each purchase, so it's RM25 for a bag of 100 fingerlings. :D

They sell commercial fish feed too. They come in 3 kinds - Starter pellets for fingerlings, Growth pellets for medium sized teenage tilapias, and Finisher pellets for those plate-sized ones... I bought a starter bag and a growth bag - each of them 10 kgs. I had forgotten how much they cost but since I spent RM76 for both the fish and the food, RM76 minus RM25 for the tilapias leaves us with RM51 for the feed.

It is now time to acclimate the fish to their new tank. At first, I just use the common "float the bag" method used to match the water temperature in the bag to the fish tank water slowly.
But then, the 1 hour journey from Hulu Langat to Kota Kemuning had stressed those fish very much. I can see them gasping for air inside the bag - a lack of oxygen? Perhaps, I should just release them in to a large container for acclimation...
|I counted... 102 tilapia fingerlings... No deaths!|

|After about 2 hours, the tank had filled up quite much. That looks like a 5 or 6 folds increase in water volume which should make the water chemistry quite similar to the water in the bigger fish tank.|
It is now time to transfer them in to their new home!
I net them out of the acclimation tank and throw them into the main tank. I disposed all the water in their acclimation tank into the drain as I don't want to risk introducing new parasites or diseases in my system.
