I don't know... Its sort of like watching these shows where people survive horrific conditions, and when asked how it is they came to survive, they say "I had the will to live." Okay, sure, but... The will to live, just like spending time to meet an animal's needs, is just the base line. Don't bother to take them on if you aren't going to bother making the necessary adjustments to keep the pipe alive. And just because you make the necessary adjustments doesn't mean that you will be rewarded with sucess.
Seahorses (and pipes, I believe) do not have stomachs, so they aren't able to convert what they eat into energy and body mass very well, so not feeding can be very serious.
All of that said, I am very glad to hear that both of you were sucessful with your pipes!
