thanks for the tips I'll check out an call my Local columbus zoo (by the way... it is in construction to be the biggest zoo in the U.S. with a huge safari)
arapaimag;448199; said:The small fish survive and reproduce because:
they are very smart
they use the 28,000 lbs of lava rock to hide in
the big fish eat some but lose interest in chasing them all the time and catching so few.
The wallegos appear to be the most succesful because they ambush capture (They lie still like a rock and just open their mouth when the prey is in range.) They do will hunt when the lights are off and pick off pish that are in the 12" to 24" range at this time. (Lights are off only during a power failure occuring at night.)
I use a 600 lb sand filter. But after so many years it no longer can handle the bio load so I am upgrading the filtration in the next 2 months.
