Basic Aquaponics - Caution of the Pacu Fish

Some how a couple of Pacu fish manage to make their way into the feeder tank and within a short time has damage the pump electrical wires.

Luckily nothing serious happens, the pump was replaced by a spare. Need to get a new pump to change.

Something must be attracting this fish to electrical wires.

Pacu

Pacu fish has grown big, this fish requires lots of dissolve oxygen otherwise they will go crazy.

Lack of oxygen they will jump out of the tank.

Palm size pacu, still long way to go.

Wonder how it taste like ?

Another Pump Failure

Guys.... WE HAVE A SERIAL KILLER... :)

Another failure with same symptom, wire damage. Look closely at the wire few inches from the pump body, sign of being nibble.

This is the second pump that fail the same way in the same tank, never had happen before. The tank was not new and I had pumps in it before without any problem.

First it happen : Here as photo below.

Initially I thought it was the pump build quality, then could it be the wire chafe against the fibre tank. The pump has been use before and the tank is not new, no failure of this nature.

I know rats love to chew on wire, sometimes we can find them electrocuted while trying to munch through the insulator. But this wire is underwater, and rat don't do scuba dive.

One possibilities... its the Pacu that did it. Only this tank has Pacu fish and I only started doing pacu this year. I never had this problem before.

Up Close with Lampam & Pacu

In-tank video of the Tinfoil & Redtail barb with guess appearance of the Pacu fish occasionally in the background.

 

This video is to do fish observation, checking their aggressive behaviour and eating style of different type of fish.

Fresh Fish For Ornamental Set

After a redo of the Ornamental set, it's time for some fish. Bought few Pacu and Barb for the two set and the third already has few tilapias.

Pacu above are at about 2 inches, they can grow big. Later I'll move them if needed.

 Barb

Leaving the fish to adjust to water temperature.

The water due to smaller space are warmer as compared to my larger sets.
