More Dead Fish This Morning

[snoopstar]

I need some help.

This morning I woke to fine 2 of my corys dead or almost dead. A peppered Cory was dead and an albino cory was very close, laying on the bottom of the tank, upside down barely breathing.

A couple of days ago a dwarf Gourami died and a few days before that another Albino Cory went. I cannot see any obvious signs of disease on them so am thinking internal bacteria? The gourami did have log white stringy poo but I haven't seen that on any of the other fish.

My water parameters. (ammonia-0, nitrate-10, nitrite-0, PH-7.5, temp-26 deg C)

I have been doing a weekly water change of 30%

I just added Melafix although am wondering if this is enough. Could it be something like columnaris and if so would I be better with Myxazin and Pimafix or Interpret 9 ?

stringy poo can be a sign of internal parasites.... not sure how your merant to treat it though

The was the Dwarf Gourami that had the stringy poo. I haven't seen it on any of the other fish but it is the only sign I have seen so far. At the moment, it's all I have to go on !

Another Peppered Cory has just died. It seems they go from swimming about fine, get sick and start laying on the bottom breathing heavily to dying within a few hours.

The fish left in the tank - 5 Zebra Danios, 1 Dwarf Gourami, 1 Peppered Cory and 1 Albino Cory all at this moment in time appear to be fine. I'm keeping a very close eye on them and have medicated the tank with Melafix today. Will water change and medicate again tomorrow.

Any other ideas?

Melafix isn't gonna do a great deal to help the situation (except help with stress) because it's designed to help with things like open sores, fin rot and mouth fungus. If it was indeed an internal bacteria infection then usuall the fish would bloat. I would also back Miss Wiggles' idea of internal parasites.. I also am unsure how to treat these though.

Ok thanks, oh and I read to myself internal parasites the same as internal bacteria. I had better start reading up on those then !!!

the normal PH for saltwater is 8.2

7.5 is just insane!

Quite possibly but mine's a freshwater tropical tank. 7.5 PH is fine for the fish I have.

Add a bacterial med to the tank like myxazin, corys are very prone to bacterial infections.
Try some shelled peas on the gourami first to flush it through.

 

[snoopstar]

Thank you, I shall give that a go tomorrow morning. So far the rest are still fine. Fingers crossed.

 

[WILDER]

Good luck.

Insane is posting that pH should be 8.2 for marines when we talking about corydoras catfish and gouramis here

Yesterday I lost another Zebra Danio. My LFS didnt have Myxazin but I did get Interpret 9 which I have also read here is similar. I treated the tank with that and later that day was when the Zebra Danio went.

Now I have the last Peppered Cory looking like its starting to struggle. My wife's just called me at work and said it's swimming looks strange.

Is there anything else I can do or am I likely to loose the lot? I will retreat the tank after 4 days from the first treatment with interpret 9 as the instructions say.

I am supprised the Dwarf Gourami is still looking good as I thought these were the weakest links in my diminishing chain !!!

Water levels are all good, amm -0 Nitrite -0 Nitrate - 10 and I did a 30% water change before medicating yesterday.

Add a tablespoon of salt in a jug of tank water stir till is disolves and add to the tank.
Shelled peas as well.

I forgot to mention I did the shelled mushed peas and they all loved them. I shall do the salt thing tomorrow. Thanks again !
