Hey everyone, new to the forum. I have been fish keeping for about 10 years now and have finally reached my show tank. I have a discus tank with a fire eel. Have had them for about 4 plus years now. Recently I changed my fire eels home. He was getting way to big for his rock cave. I only ever saw him when he would come and beg for food. Now I have above gravel in a PVC pipe. He’s really thick and has a big appetite. I feed him bloodworms and live blackworms. Now that he’s in the PVC pipe, Ive caught him like 6 times now sleeping upside down. IT SCARED THE DAYLIGHTS OUT OF ME. I tap the glass of throw food in and He’s out and about like nothing happened. I have never seen him do this before the PVC pipe. I don’t know if this is new behavior or because I can see him so well in the PVC pipe. Is this normal or do I have a problem? Please let me know guys. I love the little eel. He’s my fish baby. My husband doesn’t think anythings is wrong. Especially when we go down at night and see him roaming and “hunting”. I read a really old forum from like early 2000s that half the people said it was completely normal and the other half was said it was internal worms. Are eels okay with metro? I check my water perimeters and everything is showing up perfect. Help please.
