My boy Spike just started being all jerky, and kinda twitching all over the place. I don't know exactly how to explain it. he wasn't really swimming, just kinda staying in one place and jerking around a lot..... Anyone know what the problem could be. Oh I am also headed to the store to find some things to make new tank decorationg. The topic on caves has inspired me for some DIY projects!! I'll let you all know how it turns out.
