We all have our own techniques in keeping fish. To each their own. The basket is to get the aro eating right away. Its not meant for long term use. I've kept countless arowanas and I find they feed faster in a smaller/confined space. If the arowana was 5-6 inches sure they can go without food for a few days but small aros like this needs to eat ASAP. Its definitely not stressed. The white look is because the aro mimics its environment. WTT.
Good job with the aro so far Jay! Lets see some new pics!
