I put another fan into my aquarium recently because I felt there was not enough flow going around. I left it on for about 2 and a half days and the octospawn was very closed up and unhappy so I turned it off. The octospawn has 4 heads and two of them are doing fine, a little irritated but Other than that they look healthy. The other two heads are completely sucked into the skeleton and looks like it is falling off the skeleton. So my guess is the octospawn got a cut or scratch from something and the change in flow only made it worse. I have shut my jet off completely now because I’m scared to lose any more of the octospawn, but I also don’t want to annoy everything else in the tank that needs flow. Any suggestions???
