Didn't you not have a strainer on your pump ? I have had a clsoe call with convict in the sump. One of them got out of the breeding section and got stuck on my mag 18. Luckily he was not big enough to stop the flow. It definitely slow it down though..
Well i have 11 dats, 9 of them are I.T.'s and the other 2 are NTT's, sizes ranging from 4"-9". Most of the time they are dark in color but sometimes they flare up with their magnificent colors, Yellow, orange, white and the black bars.
