Ok, long story short, I got off bug spray in my tank. Did huge water change and replaced charcoal in my filters. My young silver arowana hasn't eaten since this happened. Which was yesterday. I know about hunger strikes and all but I'm worried something may be otherwise wrong. Other fish in the tank are eating fine except the juv rtc. He's new addition and had a really big meal the other day and has just kinda lazed around since so not too worried there. Does anyone here have experience with this? Know of anything else I can do?
