Yesterday I added 3oml of PraziPro with a 30% water change/gravel vacuum in my 90 gallon tank.  Since the medicine’s instructions boldly state 7 days is all it needs, I’ll be tracking the daily progress here.  Among other things I’ll be tracking color, eye clarity, and poo.  Yes, poo.

It appears keeping discus requires you to be something of an expert in poo.  Since discovering juvenile discus need to be dewormed every 30 days, I’ve found myself darting toward the tank every time I see the event taking place.  Fortunately they all seem to relieve themselves at the same time which makes it easy to tell which animal is having issues.

The fish in the middle is the one that has me concerned.  He’s a blue diamond, and should look like the one on the left.  Note the greyish body, dark fins and blackened eyes.  Based on the information I’ve encountered, the blackened eyes (cloud eye) can be caused by flukes, or more typically poor water conditions.  Since he’s the only one showing signs of stress and cloud eye, I feel I can safely rule out water conditions.  Some strains of discus, such as pigeon blood (pictured below), don’t generally darken to show stress, so the condition of the second blue diamond is going to be my golden compass.

I haven’t noticed any fin clamping, but the sick one tends to be lethargic and spends most of his time hanging out at the back of the tank, or away from the group in general.

After day 1 of treatment, there are no changes.  I know it’s too quick for a cure, but since I’ve never used this stuff before I’m also watching for signs of worsened stress.  One thing I have noticed is the other fish seem to be having darker bowel movements.  I can’t be sure if this is a side effect of the medication, or the new brand of bloodworms I’ve started using which claims to be worm and parasite free.

The sick one seems to have less of an appetite than before, but I’ve read a few comments from users who say their appetites might dwindle some from the medication, so I’m not alarmed yet.  I’ll do another 30% water change in two days and, of course, treat the new water.

I’ll keep you posted.

After my water has aged in my handy 35 gallon bin, it’s time to do a water change.  The instructions on the bottle of PraziPro recommends adding the medication directly to the filter box if possible.  Using a canister filter, it’s not very practical to open it up and apply the meds so I’ve shut off the water intake hose and moved it from the tank to the aging container.  This will suck the water from the container, run it through the filter, and push it into the aquarium.  Since I’m going with this particular route, I’ve medicated the water in the container for the full 90 gallons which will be distributed into the tank.

A single treatment of PraziPro left in the tank for 5-7 days is sufficient according to the directions.  It allows for treatment as necessary but no more than once every three days.  Since it gives no specific instruction on how to account for water changes, I’ll assume I will only need to replace the medication for the amount of water I’m changing out.  I’m nervous about adding more treatment at every third day, but I’m equally as nervous about not doing any water changes for 3 or more days.  We’ll see how it goes.

I think it’s also worth mentioning that some of the information I’ve come across recommends giving juvenile discus worm/parasite treatments every 30 days.  Apparently the discus can come in contact with the parasites through their most beloved food… the bloodworm.  From what I’ve gathered, adults are generally capable of warding off or safely dealing with the parasites through their own immune systems… but as juveniles they are more susceptible.  I cannot guarantee how accurate that  information really is, but it sounds legit. . . . besides, an ounce of prevention is worth a pound of cure.

I’ve also come across a bit of information that would indicate discus don’t react well to salt in their water, so starting with this water change I’m phasing salt out of the aquarium.  If this proves to be problematic, the frequency of water changes that discus require will make it easy to re-introduce salt to the tank.

At any rate, the tank has been properly medicated and now I can only sit and wait.

Wish me luck!
