Michael, fish are creatures of habit, and almost never jump at new food. It will take them a while to get used to it. It helps to blend the old with the new, and gradually wean them off of the old. Or you can do what I do, and feed the fry the same thing you feed the adults. I used to grind up larger pellets, but now I don't even do that. I just toss in a handful of whatever I'm feeding. Tilapia will do well on whatever you feed them. They nibble away from the pellets, and the pellets soften…

Tilapia will do well on whatever you feed them. They nibble away from the pellets, and the pellets soften throughout the day. I also feed mine duckweed and rabbit food, fry fry stage on. Fry less than 1" long will go for both, and once they get over 2" long they prefer the rabbit food over aquamax 4000 or duckweed, and grow very fast on that diet.

<p>If it doesn't need to be super flexible Michael, you might be able to use some of the black HDPE waterpipe instead of vinyl hose. I'm not terribly worried about ridgid pvc (except when it becomes brittle and gets broken easily later after years out in the sun) but the flexible vinyl, even if given a "food grade" or "potable water grade" rating I still am trying to avoid it where I can.</p>

<p>This has been a great concern of mine too but I have been very frustrated in my efforts to purchase other kinds of pipe. I have a 5000 gallon cistern under the house and all the pipes are PVC.

<p>I have approximately 50 fry in my tank. I graduated them to the slightly larger food yesterday since they got to be more than 2" long. They went for it right away but didn't seem to eat as much as with the powder. Very quiescent in the tank afterwards. I am concerned that some of the smaller ones won't be able to eat this larger food and put in a little of the crumble as well but they didn't seem interested. What has been your -- anyone's -- experience when you switch the food. </p>

Banding Patterns and Coloration<br />
<br />
The main cultured species of tilapia usually can be distinguished by different banding patterns on the caudal fin. Nile tilapia have strong vertical bands, Blue tilapia have interrupted bands, and Mozambique tilapia have weak or no bands on the caudal fin. Male Mozambique tilapia also have upturned snouts. Color patterns on the body and fins also may distinguish species. Mature male Nile tilapia have gray or pink pigmentation in the throat…

Nile tilapia have strong vertical bands, Blue tilapia have interrupted bands, and Mozambique tilapia have weak or no bands on the caudal fin. Male Mozambique tilapia also have upturned snouts. Color patterns on the body and fins also may distinguish species. Mature male Nile tilapia have gray or pink pigmentation in the throat region, while Mozambique tilapia have a more yellow coloration. However, coloration is often an unreliable method of distinguishing tilapia species because environment, state of sexual maturity, and food source greatly influence color intensity.<br />

Post a picture if you can. Color and banding are quite variable. I've seen my Salton Sea tilapia range from dark black with red fins and blue jaws (breeding male) to very light gray, almost white (same exact fish). Water temp, water chemistry, and environmental stress play a huge roll on coloration. That being said, my pure strain mossambicus Hawaiian Golds always look the same (or very similar) with a slight darkening of the face on the dominant male.<br />

By your description, they do sound like Niles, or Nile hybrids, I've not heard of pinks in the mossambicus strain, or vertical bars. I'd call your source and ask them, and demand proof. DFG may do a genetic test for you, if you wish to get them involved.
