yes sir it is self collected. i have yet to ever buy a single piece of wood. every piece i have i find. i have no idea what kind it is. i found, liked it, cleaned it and bam..in the tank it went. i just added a new piece to the 75 yesterday and will be adding another piece when i get back from florida, its still soaking.
all i do is find wood thats not green and has been sun baked for a while. then i clean em off ( cold water ) then i soak them in a tank of hot water til they sink. do water changes on it once or twice a week as well
To those of you who were talking about your angels eating other fish... I have a question. I broke down an old 10g the other day and dumped all its occupants (about 50 three month old guppies destined to be dinner anyway) into an angel tank. I have a blue blusher who chased the two dozen or so that didnt get eaten and attacked them one by one... only biting their heads off, spitting out the head, and continuing on to the next guppy. Whats the deal with that???
