i feed my fish twice a day, and i only feed what i can see get eaten in about two minutes (because they get fed twice.) they get flakes about a half hour after the lights come on, then a half hour before the lights go out. they ALL come to the top to eat. it's funny seeing a 13" pleco completely vertical sucking at the surface for floating flakes. it usually gets special treatment as i have grown accustomed to handfeeding it flakes and bloodworms. my redtail has developed a great personality since i added the new fish in september...it now with flip upside down and nibble at floating flakes. it has also gotten better at catching sinking flakes in it's mouth, so it still missed a lot of times. i'll typically drop in three or four algae wafers at night, and on sunday everybody gets the weekend special: bloodworms! on sunday, i only feed at night.
however...
last night i hand fed my pleco a slice of zuchini for the first time. he/she went absolutely nuts over it, so did the red tail shark. at one point, it latched on so tightly with it's mouth that i could pull it and the zuchini around the top of the tank. i could even see him eating the seeds as they came loose. after there was a sizeable hole in the zuc, i went out to the kitchen and cut up two more slices for the veggie clip. this morning when i woke up, both slices were about 90% gone. i have some romaine lettuce that i'll try tomorrow. i'm very excited about this because i had a feeling that my loaches were getting all the algae wafers i was dropping in. i also don't recall seeing the long pleco poops for several months. i'll probably keep up with the zuchini, and cut back the algae wafers to one or two per night.
everything is fresh..i don't like the idea of softening the veggies by boiling, although spinach leaves might be an exception. they should naturally soften up after a day in the tank...
