I have myself to blame...
Cycled my 200L new tank for a month. I thought to myself, not bad.. patient enough..
Well, as I only have 1 chiller, I decided to transfer all livestock in one session. I'm also fully aware that the new tank can barely take the sudden increase in bioload. I still insisted to go ahead..
On the morning of transfer, I went to the farm to get T5 parts. Saw this beautiful powder blue tang. Not the usual pbt, but one all the way from Maldives.. The colours were.. wow.. and the size was only 2"!!
Needless to say, I succumbed to the temptation.
Went back home, left this bag of pbt aside and got down busy to replumb the chiller, return pump, and all what-nots, and transferred the livestock.
In my busy-ness, I totally forgot about the bag of fish! And guess what, I left the bag standing on the floor for more than 10 hours! I only remembered I bought a fish when I was about to fall asleep at night.. Lol..
Instead of wanting to introduce this pbt first to reduce stress, now I added him last!
White spots were observed the very next day. Feeding garlic-soaked food didn't help. Tried to catch him out but hugely unsuccessful. He was gone in 5 days.
What's more, my fat blue tang and juvenile Atlantic blue tang got infected too..
At least the blue tang is feeding well, and he'll recover pretty soon.
For the juv ABT, the spots got more, and he completely lost appetite.
Finally managed to catch him out yesterday and did fw bath. He didn't make it overnight too.
Lessons learnt..
1. Never ever be in a hurry to add any livestock your tank cannot yet handle. This, my friends, is the cardinal sin.
A similarly good, if not better, specimen will always come in a later date. if it's meant to be in your tank, it will be in your tank.
2. Do not attempt to transfer livestock to a new environment all at once. I should have taken my time to transfer the corals first after plumbing in the chiller. At least I would have time to place then nicely. Fishes can take the higher temperature for a day or 2 more..
This ought to teach me a valuable lesson on patience.
