Did all your fish come from Hans or did you start out with a few LFS store fish and then add some from Hans?

does your tank still look like this:



http://forum.simplydiscus.com/showth...t=#post1098305


You state you have 0 ammonia 0 nitrites and 0 nitrates. Is this a guess or do you have a test kit? 0 nitrates is next to impossible with your water change regime and a cycled tank.

Are you using straight Ro/di water with no tap mixed in?

Do you have a QT tank?

Can you post some recent pictures of your fish and your tank?

[new2discuss]

My tank looks like that still and yes I have a test kit I only use ro water I do not have a qt tank the tank its self is about 6 years old had many healthy fish in it for years oh and I started with two fish from the lfs but she buys them from hans it was cheeper that way the other thing I noticed though is that my plants are dwindling the tank temp is at 82 to 84 degrees I do have substrate in it and one fish went down a little before and I treated with a parasite gaurd from I believe tetra I know bad but I don't have a choice for other reasons I have to buy from the pet store but I was after prazi which this had in it and that worked for the other fish a turquoise but the one fish that died never came out of it he just seemed like he was getting better then he fell right back down so I tried this again and its not working the little blue diamond still won't eat I did some research on it and something called hex come up and that same parasite gaurd had the medication reccomended for that so I treated again about three weeks apart .... the only thing these fish are doing is getting dark and not eating the other four fish are fine absolutely happy as can be growing very well .. once in a while they'll flick there fins when they are excited .... but you should know that one fish has a red mark on his body where it looks like she was fighting and lost a scale but the fish dosent seem upset by it at all

[new2discuss]

My fish now appears to have sonething that looks like black mold growing on him ...he won't let me get a picture ...and I know ots not mold but that's exactly what it looks like little black patches on his body

[new2discuss]

I apologise in advance I can not coppy and paste the form I am supposed to use but here goes ph 6 temp 86 5 fish almost no nitrates or nitrate or ammonia I use ro water only the onky chemicals I'm putting in my tank is discus trace and plant fertilizer and I change water every other day 30 % for my 50 gallon tank. I have a blue dimond who was just hiding in the corner turned dark and now he seems to be growing what looks like black mold on his body (I know its not really mold) it looks just like black mold growing inside a cabinet. I had another fish die but I never saw black stuff growing on him but it could be because he was so dark I just couldn't see I have tried parasite gaurd it didn't seem to do anything . My little fish is not eating and he is getting very thin I'd like to not let him go. Please help

So all your fish are from the LFS, just that the LFS buys from Hans?


We need to see pictures of the fish as they are now, not how they were when you first got them.

If you want a reasonable chance of medicating these fish (should it be necessary) you will either need to get a QT tank or remove all the stuff out of your display tank (gravel/fake plants/no fishing sign/clay skull/etc etc).

As for the "black mold" can't say I have ever seen this, really need to see a picture. It would be nice however if you did not have multiple threads running concurrently, no need for that, it only confuses things.

Based on what you have told us so far, I am pretty certain that the majority of your problems are water related. I would start adding 25% tap water (dechlorinated) to your RO water, do 80% or better water changes daily for at least the first week (once things have sorted themselves out we can cut them back a bit).

Please report back sooner than 2 weeks this time. We are glad to try to help, but that help is more easily given to those that put the time and effort to get us the information we request

We really need to see a pic of this please.

Thanks,

Once the fish hit the LFS it is not really fair to call them Hans discus. They were exposed to everything that the local store has. Not sure about the "black mold" deal either but a picture might help.

I'm gonna guess pepper.

[pcsb23]

I'm gonna guess pepper.

My thought too.

[nc0gnet0]

I'm gonna guess pepper.

How did I not think of that?

Ok, I merged the threads. The affected fish with the dark areas is a blue diamond according to the OP in post 5.
