Hi mfk...

In the last couple weeks my aquaria has been a wreck. I've got two disasters on my hands, or one disaster and one worrying potential problem really.

Here's how it goes:

Problem 1 - Preditor tank with breif ich outbreak. A ropefish came in with ich and showed signs of it about 10 days after buying. I upped the heat, offed the lights, and treated with Nox-ich for days. It appears to be gone now, but my ropes are nearly non-existant in the tank now, one has a tiny red nub at the end of each nostril, and my bichir had a pinkish blush spread over his fins, gone now. I breifly put some anti-biotic (EM) in there food after noticing the pink.
Current Situation: The ropes are still missing from the swim-scene, and the one rope still has red nostril tips. Ammonia reading somewhere between 0 and <0.25

DISASTER - This tank is a mess. It's a 55g sporting various loaches, guppies, and other fish. A few weeks ago I got a weather loach and all seemed well. A couple weeks ago I got 8 glasscats, and there's where the problem began. (My stock was a bit high pre-glasscats, but 8 of them shouldn't have caused this kind of a problem, right?)
-Day of glasscats: One seemed to disappear 5 minutes out of the bag. They were carefully acclimated. 7 were left by the end of the night.
-Roughly a week later: I believe a glasscat died in this period, but the notable point was the deaths of my betta, a guppy, and a sumo loach overnight. No symptoms. No glasscat bodies. Was lightly treating for ich around this point in fear of infection from other tank. Melafix as well.
-Days following: Glasscats sickening one after another. Turning white, swimming on angles, dying. Only two bodies found out of 5 dead bodies. Frequent waterchanges throughout this whole thing. Kuhli loaches becoming considerably more lethargic and some hanging around the top of the tank for long periods of time.
-Current situation: 3 cats left, seem to be stable other than very short whiskers. Are eating. Two kuhli loaches found dead, one several days ago and another one today. Other kuhlis have seemed lethargic, wilted barbels in some, and one currently has two barbels very much shortened with red nubs at end. One guppy has been kind of wobbly for a while now, but all other fish seem fine. Have been treating the food with antibiotic. Ammonia readings 0.25ish. 10 fish dead following glasscat arrival, some with mentioned symptoms other without.

What is killiing them? I need to stop this soon, I can't take anymore dead fish. This whole thing is breaking my heart. Between nox-ich, melafix, anti-biotic, no symptoms other than lethargy and damaged barbels in the kuhlis... What else can I do?

Please help. I'm at my wit's end.

How long has the tank been running? Give us all the details you can. Filtration, aeration, wc"s etc. Also a list of tank inhabitants. Rope fish are notorious for escaping. Have you looked outside the tank?
 
The pred tank is 70g with perfectly running everythings. The ropes are int he tank (checked last night), they're just hiding... all the time. It's unusual for them. Inhabitants are the three ropes, a young bichir, and a bushy pleco. Running a few months now.

The community tank (disaster tank) is a bonanza of bottom and top dwellers but nobody is aggressive or within anything else's nom range. I'm about 10g overstocked, but I inch-per-rule a lot of the thin guys like the loaches. All the equips are working fine in there too, though the carbon has been removed for the ich treatment. Running almost a year. Also has an air stone to help the weather loaches in the warmer temps. Thankfully they're doing okay, they're the 'centerpiece fish' of that tank.

Both tanks get a 25-30 percent wc weekly while I'm gravel-vaccing. My water perams are excellent. My other two tanks (a 10 and a 20) are doing just fine.

So discouraging.
 
So if your doing everything right what could be your problem? once your tank is fully cycled these problems dont happen. its a cycle.....learn to ove it
 
Be careful with nox ich the stuff is pretty powerful. Loaches especially kuhli loaches have no scales so the nox-ich could be burning them (thus the red around nostrils. I would use it half dose because of the loaches and bichers.
 
If you have ammonia readings your water parameters are not excellent. My best guess without pics or seeing the fish myself is that there were sick fish brought in (with ich, flagelletes or whatever) and this weakened the other fish and let some other nasty bacteria take hold (the ammonia is not helping things either). Columnaris would be my best guess and EM in the food probably won't cut it because the sick fish need to eat it before the meds leach out of the food and this is unlikely. Your best course of action is to get the sick fish into QT and treat them with them with antibiotics like manamyacin + furan-2, oxytetracycline or the maracyns. This is assuming you have the ich beat and lots of other assumptions so without actually being there this is IME.

When everything does shakeout seriously consider getting a QT tank.
