We also feed Omega One Veggie Micro Pellets along with other staple Cichlid flakes and Pellets 2x / day Food Fed to Fry and How Often: 2x / day — Omega One Veggie Rounds, boiled slices of Zucchini (green squash), Occasional Sera-O-Nip tab, ample wood and oak leaf litter for fry to gnaw on Photos Comments & Additional Information We have always kept at least one Bristlenose Pleco in each of our tanks that are 20 gallons or larger. We started out with our African Cichlids a year ago, bought a bright assortment of young Mbuna, and tossed in three Bristlenose Plecos to help cut down on algae growth. They do keep the tank spotless. Because we feed our Cichlids a variety of foods, including Omega One veggie micro pellets, the Plecos are well-supplied with a rounded diet. Beginning about four months ago, we discovered that one of our plecos was starting to grow out his cupule mouth structure. Very quickly, we observed that he had found a narrow crack in the Texas Holey Rock, and was wooing in a female. They spawned, and we eagerly watched as the eggs hatched. However, in a fully stocked African Cichlid tank, it is difficult for fry to survive. We watched this scenario happen twice - requesting advice from more experienced breeders in PVAS - and finally determined to pull the eggs. Pulling BNP eggs proved challenging. They were laid in a tricky little crack at the bottom of a 100-lb. chunk of Texas Holey Rock. We had to use a siphon to scrape them loose, and draw them down into a specimen container suspended over a pail. Once set up in the specimen container with a bubbler, and touch of H2O2 (ca. 1/2 ml.), they all hatched beautifully in five days, and the rest is history. They ate off their yolk sack for a few days more. We put in some Wisteria and wood which they all took to. We were advised to get them into a tank with a lot of wood! We built a little 5.5 gal. grow-out tank with a sponge filter, bare bottom, java fern, and loads of wood. The Plecos absolutely love boiled zucchini, but need some food with protein in too. We feed Omega One Veggie Rounds, some sera micron dissolved in water, and an occasional Sera-O-Nip tab (krill-based, heavy protein). Within about three weeks, we began to distribute the growing BNP fry to other tanks. 20 of them went to a 55 gal, housing a large grow-out population of German Blue Rams. 10 of them went to a 40 gal breeder housing a mixed grow-out population of Auratus and Kribensis fry. Another 10 went to a 20 gal.-long where a younger batch of rams is growing out. The key to every tank they are moved into is the presence of ample aged wood.
