I am having a dilemma with my 29 gallon community tank. Up to this point this tank had been going very well. I aquired 6 marble hatchetfish a couple weeks ago and within a few days 4 had died. The 2 remaining ones are doing quite well and look great BUT I now within three days have lost almost all of my ten neon tetras that I have had for at least 6 months. They are just dying off several a day. I noticed one of the two remaining ones has white cottony stuff on its head like ich. That is the only one that has shown any evidence of any disease before just dying. Do you have any idea what could be happening? Any suggestions for treatment? I now only have 2 young angelfish (that look and act fine), the 2 hatchetfish, 3 three-lined corys and 1 oto cat (I intended to add more otos soon) and a mess of cherry shrimp. This tank is heavily planted and all my water perimeters are fine. I am afraid if this is neon disease I have read about, the entire tank is doomed. Thread started.
Bryon, yesterday I added 6 marble hatchetfish to my 29 gal community tank. It is heavily planted and everything has been doing great. I gradually added tank water to the hatchetfish and checked the pH in their bag. It was 7.2 and my tank is constantly 7.6 but the GH KH is between 50-100ppm. I can not get my pH lower. I have boxwood, oak leaves and have recently added Indian almond leaves. I am concerned my water might be too hard for the hatchetfish. Should I be concerned about this? No, I see no issue. Even at its hardest, 100ppm is only 5 dGH, and I raise my GH to 5 and 6 dGH and I have a large group of wild-caught hatchetfish, both Marble and Black-winged. GH is actually the more important. The pH may lower as the tank matures; if you want to pursue this, start a thread in Freshwater Aquarium. B.
Thanks Bryon. I didn't find your response until today. I guess I didn't know where it was posted. I contacted the seller of the driftwood and he says the wood is NOT cedar. I have put the pieces I bought in the aquarium and so far, so good. How soon did you notice you had a problem when you had driftwood kill half your fish? What wood do you recommend? If the wood begins to get real soft and basically rot, take it out. As for anything toxic in it, this is impossible to determine until it leaches out. I've only once had this occur in 20 years, and it was with some softish wood that in hindsight might have been cedar or similar. Since then I use Malaysian Driftwood, sometimes called ironwood; is it very dark brown, hard, and heavy, it sinks immediately. B.
Hi Bryan, I just received 2 very lovely pieces of old driftwood I found on ebay that was advertised for aquarium use. It floats and one piece smells like cedar. It looks like it has been aged in water. Should it be safe to use? Thanks, Grannyfish I would not put cedar in an aquarium. Being a very soft wood, it will quickly decompose. And being soft it also absorbs substances more than hard woods and these can be toxic and leech out quickly. I had this occur with wood from a store years ago, killed half my fish before I realized what it was. B.
