What I did to achieve the target that didn't tell you guys earlier is the help from my maid. I monitor the fish closely and feed it myself in the early part of the morning. Bought the maid a count down timer and give her the feeding timing (note: every morning will be different depending on my observation of the fish that particular morning). And, teach her the important things that she need to notice each time she feeds the fish; such as unfinished food, bad water, etc. And what to do each time she encounter those mentioned problems.

The body is not as thick as i desired therefore need to work on the digestion timing. No point for them to keep eating and doesn't digest well. the poo seems good, proper color, submerged, round and each 10-15mm long.

at the beginning, there're mild sign of indigestion. During this water change, I've added in 0.5% salt to help a little. Result is very positive.
