Dear All,
After the last unsuccessful batch of fry, we have had a new batch of approx 50+ from March 15 (~3 weeks old). We have taken the advice from the last thread very seriously and we increased the frequency of our WC. Things were alright until today: We found one fry had died. We are extremely disturbed and clueless regarding what may be the issue and are very afraid this will start another epidemic amongst the remaining fry population.
The following are the details and pictures are included at the end:
1. Please explain the problems with your fish. When did you notice the problems and did anything unusual happen that you think started them?
Fry had passed on upon our return. We did not see any prior problems such as gasping, scratching, lethargy, etc. The fry were all eating voraciously as per normal.
2. Symptoms (i.e. turning dark, excess slime, not eating, clamped fins, flashing, darting, clamped gills, white/yellow/green poop, hiding, headstanding or tailstanding, white on tips of fins, rotting or fungus, blisters/white zits on fish, bloated, cloudy eyes, wounds).
Upon death, found strange orange and black-looking growth on body. Fins were ragged, mouth open. Upon netting, we also found a red worm-like looking thing, not sure if it has anything to do with the death of the fry. We certainly did not feed any worms or live food. This particular fry is one of the bigger ones in the tank.
3. What medications/ treatments have you already tried and what were the results. Include dosage and duration of treatment.
Mild dose of API pima and mela fix and Sachem Prime due to one of the parent's slight injury (probably due to fry latching for feeding).
4. Tank size and ages, numbers and sizes of fish.
20 gallon tank. 2 adult discus, ~50 fry.
5. Water change regime (What percentage and how often).
25-50% daily WC. Grav vac daily after feeding.
6. How long has tank been running? Is it bare bottom? If you have substrate, what type and how deep is it?
Last 1 month. Bare bottom.
7. Do you age your water? If you do for how long and what is the ph swing.
Using aged water.
8. Parameters and water source:
- temp: 27C/81F
- ph: 6.4
- Tank is cycled
- ammonia reading: 0.25 ppm
- nitrite reading: 0 ppm
- nitrate reading: 5.0 ppm
- Dechlorinated tap water
9. Any new fish, plants or inverts added recently.
No.
10. Extra info regarding diet.
Oceanfree instant BBS for fry and FD Blackworms for parents (fry occasionally nibbles).
11. Include any pictures or videos you have which shows the symptoms. If you can't add them to this post, please provide a link to them.

This is really quite alarming as we have never come across such an odd looking death. Would really appreciate it if any one is able to shed some light on what may be the cause of death and any precautions we may have to take for the remaining fry as well as parents.
Thanks in advance.
