In the last few days my fish suddenly got more aggressive and voracious than I ever saw before.
The 20" black arowana that I was worried about because she hardly ate anything, aggressively swallowed 5 large shrimp both yesterday and today. The 10 shrimp might be more than she ate in the previous month or two. And I am sure she'd eat more, but I have to go and buy shrimp.
The 10" Crenicichla Semifasciata used to come up for food lazy, swallow lazy, chew a bit and spit it back out. In the last few days he has been staying on the surface wagging his tail and when I start feeding, jumps out of the tank and swallows everything without even chewing. Just now he jumped and bit my finger. It is a 1/2" cut and bleeds. This guy is usually friendly and lets me pet his huge head like a real pet.
There are two explanations for these sudden changes in behaviour I can think of:
1) The quality of water in the pipes of Buenos Aires suddenly improved and the fish started feeling better after WC one week ago.
2) Some change in the weather makes them hungrier.
The first explanation seems more plausible. However, the Lungfish also seems more active and hungry and I doubt he cares about water quality.
As to the second explanation: The atmospheric pressure has been high for a few days. Being a weather sensitive creature myself I can tell - it is good weather. I feel good and I feel it is like a good weather for fishing.
What are your thoughts?
