fish systematically dying in 55
Soooo, it started with the swords, then corys, now my rainbow shark is in the midst of slowly dying to whatever is affecting my fish. I assumed it was poor water quality for a long time just because it was so slow going, but now its not just the swords, its affecting my other fish as well in exactly the same way. Starts with lethargy, they may or may not eat, may or may not have clamped fins. in the later stages they get white fin edges, ragged edges, and white raised blotches on the skin, which is most notable on my rainbow shark.

lets see... 55g, fed flakes and a couple wafers once a day, water changed at least 2 times a week since the fish became sickly, several large aquarium plants in there, ammonia is 0, but thats the only reading i have, filters are a hydro sponge IV, and a penguin 200. penguin gets swished when the water flow slows down. not previously treated with anything.

any ideas?

Dang that ain't good news to read there from ya, I'm sorry!
Almost sounds like some parasite attacking them all had you sifted through the sickness sticky note here it had a lots picture references too?

yeah i have, nothing matched well enough for my liking though. heres the weird thing. all my fish of all types in that tank were affected the same way, with the same progression for everything, so im ruling out high nitrates causing stress.

the weird thing, is we did another water change last night, as we have every few days for a while now... and this afternoon the white spots are gone and his behavior is right back to normal. I guess ill have to pick up some refills for my master kit and keep an eye on it, but its too weird for me.

That almost sounds like some sorta internal parasite that spreads amongst ALL them and then leave visible signs later on?

If the latest w/c helped as in fish getting visibly better/ not dead then maybe do some w/c each 2-3 days for right now till its all healed up for everybody? You can indeed do a lot about fish sicknesses just by clean water supply. That is extremely odd thou...

What you've described is associated with bacteria. This is due to poor water quality, which would explain why your fish improved after you started doing regular water changes.

Try more frequent water changes in the future, and siphon your substrate when you do. Don't forget to age your water prior to doing the changes.

no no, they all got worse, been doing the water changes every couple days for a couple weeks now... it was only after the last water change that it all magically improved. I added a ton more plants last night, hopefully it will all balance out nicely :)

Have you by chance changed the water conditioner? Maybe you got a hold of a bottle that's past its shelf live and so you're adding stuff from the tap water that does not help them? ....Just trying to think of anything that could be a reason...any way to help you there.....

Sounds like a parasite, the water changes don't help when it's attatched to the fish but if you get it while it's freeswimming then it can't reattach itself.
