Fish food

My hubby rare lot of kelar fish in the house now. He treated them as his pet too. Everyday after work, he will quickly see his fishes first. Then feed them some fish food before he enter the house. Occasionally he will call back from office, remind his girls to feed his fishes too. Hmmm…look like he already treated the fishes as one part of family members too. He wishes to feed them till bigger size, and then sell for a good price in future.
