Help! For the second time a same strange disease has wiped out only danios in my 34-gallon tank. I only have two left and I'm trying to put a stop to it. :sad: Both epidemics went through the same phases, and in both cases all but one danio got sick. It starts when a couple of danios die...

I have a pathetically sick danio that simply refuses to give up the fight. It's amazing he's still alive, given that he probably hasn't eaten for a couple of weeks. He mostly hangs at the top of the water, body limp. Every now and then he suddenly starts shooting around the water, twirling...

I have a male platy in an established tank with good water parameters. Several days ago he started to lay around the bottom a lot, and became increasingly bloated in the abdominal area. He has now been moved to a one gallon hospital tank. He refuses to eat. Every now and then he rises to the...

After a couple months of trying to fight off a danio "mystery illness" with 2 ich treatments and anti-bacterial treatments, we had green chemical soup in our tank. After a few water changes, it was still milky looking, probably from losing some of the cycling to the antibiotics. Even after all...

We bought a dojo loach yesterday. Today we couldn't find him anywhere and took the whole tank apart to find him. Finally we spotted him stuck at the back of the tank. We have a 34-gallon red sea, which can be used as a freshwater or marine tank. The water passes through a grate on the right...

A strange question, I know. But I've been keeping fish long enough now to know that sometimes seemingly healthy fish just die for no apparent reason. The water stats can be fine, everyone seems happy, but a fish suddenly loses steam and never recovers. When there are symptoms, it's easier to...

I have 2 male platys in a tank. One harasses and chases the other. Tonight my female in another tank died and I am considering moving her "mate" in with the other males. But he is smaller than the other two. Would 3 male platys in one tank with no females get along?

I have a neon tetra in an established 14 gallon tank shared with 3 other tetras, 2 adult and 3 tiny baby platys, and one cory catfish. I don't have water stats but can get them from the LFS in the next couple of days. In the past month we have lost one other tetra and a golden algae eater, but...

Five of my 6 zebra danios were wiped out by a mystery disease that affected only danios. The last one died this weekend. Somehow the sixth danio never got the scourge, and appears healthy and strong. But now he's all alone. I have 5 more danios in another smaller tank. But would it be a...

Hi there. We have four tanks, and only one has a compartment designed to put a bag of ceramic filter media. For the other tanks, our LFS suggested that we can just put a mesh bag filled with the ceremic rings directly into the tank water. Is this good advice? How much good (or harm) would it...

Hi there. I have a 34-gallon Red Sea tank. It can be used as either a freshwater or marine tank, and I use it for freshwater. The lights on the tank are very close to the top of the water. With lights on, the temperature can go as high as 82 degrees. But even with lights off, it rarely...

I just had my water tested. Ammomia is 0, nitrites 0, nitrates 10, pH 8.5. The LFS worker said the pH is high and recommended Seachem Neutral regulator, which adjusts pH to 7.0, plus dechlorinates and removes ammonia. I'm hesitant because I've read that sudden changes in pH can harm fish...

We started with six danios that we've had at least four months. Four are left, and two of those are showing symptoms. No other fish appear affected so far. Thanks for any advice you can give! Tank size: 34 gallon pH: 8.5 ammonia: 0 nitrite: 0 nitrate: 10 kH:? gH:? tank temp: 81.2 F (ranges...

For about a week or so, one of my danios has been acting strange, pacing near the bottom of the tank, but still eating. He didn't appear to be scratching himself, just acting different. We did our weekly water change but didn't notice a lot of difference. Still he had no other symptoms until...

Hello all. I have a danio in an established 34-gallon tank that has been acting strange for the past few days. Instead of swimming around with the rest of the danios near the top of the tank he (she?) has been "pacing" back and forth in the same spot near the bottom of the tank behind a cave...

We have five danios in an established 34-gallon tank that has been operating for several months. I'm sorry I don't have water parameters right now but I can go to the fish store to get them if need be. One of the danios has been acting strangely for the past 2 days. Yesterday, he appeared to...

Hi there. I'm setting up a new 15 gallon tank, and have not added any fish yet. I rinsed filters from two of my mature tanks into the water of the new tank, and all sorts of lovely gunk came out. A couple days later the water was cloudy looking, but unfortunately fibers from the filters I had...

Last night I seeded a new 15 gallon tank by rinsing filters from two other tanks into the water of the new aquarium. There are no fish in the tank at this point. This morning, 8 hours later, there are numerous long white/clear threads hanging from all the plants. Is this some type of bacteria...

I am starting up a new 15 gallon tank and would like to speed things along with filter media and/or gravel from my other established tanks. How do I go about doing this? All have different types of filter systems or cartridges that can't be substituted into the new system. Thanks for any...

I have one golden algae eater in each of my three tanks. I believe they're related to chinese algae eaters. Unfortunately, the LFS sold these as ideal algae eaters without telling us about the flip side of their personalities as they get older. This weekend, my largest CAE started divebombing...
