Thanks for the help fishpeeps. I think i'll leave him in for now. It would take me forever to get him out of the cave he is chilling in (it is the bottom support of a much larger, barely stable structure). Besides the tetras are sort of expendable since they were free and i could easily replace them (or switch out the knifefish if i put my mind to it). I'm also gonna give away my checkerboard cichlids to a friend for a while (i might take them back someday).
Right now the knifefish just hides in a cave and moves forward and backward over and over again. It is kind of funny.
I haven't gotten him to eat yet. I think he may have nibbled on a piece of krill but then he just knocked it out of his cave.
On the bright side, i saw my eel eat for the first time today. He did it right out in the open with the bright lights on too. He is finally getting used to the tank. Will the knifefish take a similar adjustment period (5 weeks)?
Also, now that i work at a fish store i could easily replace my smaller fish with bigger fish as the knifefish and eel grow.
