Got two at the same time. Male and female. Only one remains to date - male
1. How often do you do water changes? one a week
2. What percentage do you change?1/3
3. What size is your tank? 7'x2'x2'
4. What is your stock? 3 silver aros, jar, green aro and endli bichir
5. What is your filtration? overhead + internal tower thing with bioballs + water heads + sponges

7. How often do you feed your rays? two times a day
8. How long have you maintained this schedule? until now
9. Barebottom or Sand? bare bottom
10. How long before your ray stopped eating and its death? was eating up to its demise. No warning and no outward signs of illness
11. Did you add salt for treatment? with the exception of outdoor set-up, all my tanks are salted (1 table spoon for 5 gallons) with non-iodized salt. Water treatment for decholorination with de-chlorinator each time.
12. What other meds did you use? i only use malachite green in dire situations
13. Did you transfer the sick ray? no - sudden death
14. What other info do you think might be helpful? Water in Vientiane is pumped from Mekong river and is treated with chlorine derivative. From time to time, the water tests positive to presence of chlorine
15. Where was your ray from? Vendor? CB? Wild Caught? CB i believe - from Thailand
Can't imagine that the winter would have anything to do with it IF our flood didn't. The water level of Clear Lake was higher than it has ever been, no ill results that I have experienced in terms of water quality.....
Once or twice per year many muni water supplies will put a huge 'slug' of chems through their system to reduce bacteria etc. athough usually during warm weather. Another reason to age and prefilter your water.
How many of these sick rays are either themselves from Asia or have been in direct contact with fish from Asia? I bet nearly all of them!
This kind of stuff was rare before imports from that part of the world became more common. Wild caught rays hardly ever bring bacterial problems with them. This is well known in fish circles for other species bred in Asia, the infamous 'discus plague' is an example that did the rounds globally several times over the years. A nasty and mostly antibiotic resistant bacteria that quickly destroyed whole breeder set-ups before it could be treated or diagnosed.
QUARANTINE all incoming fish for at least a month, preferably in a seperate room. Bacteria can move from tank to tank in a single drop of water or even through the air. Wash your hands before and after you touch your tanks. Cleanliness is next to godliness!
Rays are better kept as a single species. I see people here mixing rays with all sorts of fish that are not good tankmates and which complicate all problems because of their conflicting behaviour and habitat requirements. Every time you add another fish you add a bullet to the gun you are playing russian roulette with.
K.I.S.S acronym is usually attributed to kelly Johnson, the designer of the U2 spy plane. Simplicity is sophistication.

11. Did you add salt for treatment?

12. What other meds did you use?
furan 2 (wasn't really tested till me and it wasn't good) and nitrofurazone

no

My flower and 2 leos all where slightly affected but recovered. They were with me for awhile. I added two new w.c. xingu's and no problems added 2 more and noticed white around the edges of one of my first xingu's. They never stopped eating till the addition of furan 2 and some never ate again. Some did start eating but slowly stopped over time.
15. Where was your ray from? Vendor? CB? Wild Caught?
wild caught brazil
My water is from a community well and we are not at our run off season yet and I have talked to the county and there has been no changes to the way they treat the water.
I dont know, im assuming from a municiple since im located in a city of about 25,000 however Im in a school town (town home). Ill be moving to a municiple system in May when I graduate. and winter hasnt been to bad, it started out with alot of snow but we havent had any for a while, its been pretty cold laitly though.
The only time I lost a ray was doing direct water changes and yes the water being added was the correct temp and I used a conditioner. The ray stopped eating and was acting strange and died in about 2 days. I noticed the tap waters PH was much higher than normal and I think the water was also very hard. Now I let the water sit for 24 hrs and get the PH right first.
I found in the winter months my PH from the tap goes way up so the town is adding something to effect the PH and KH.
You might want to add weather the water changes are direct or allowed to sit over night.
