1~What type of fish is afflicted? In addition, please describe what is wrong with the fish to the best of your ability (i.e. cotton like growth, bloated, etc.).
A:
- A Red Irian rainbow (dead) - had something white sticking out of the anus for a few days and refused to eat. 1-2 days before it died it belly seemed to cramp into a ball(not bloated) and then it died. When I took it out of the tank it had something like a wound on the side but it might've been due to other fish picking on it when it was weak.
- A rummynose tetra(dead) - came very skinny right from the store. I thought it was underfed but it was likely sunken belly or something. It died 2 days ago.
- A rummynose (white mouth) - can't tell if it's discoloration or growth(check the video below). It looks a lot like how rainbowfish's mouth looks like when it gets damaged by a fish net.
- Turqouise rainbow (not eating) - I noticed this one a few hrs ago(it's the rainbow I zoom in on in the video). Visually there are no symptoms but it doesn't really swim around - it stay in one spot and doesn't show interest in food .
2~What are your tank parameters (ammonia, nitrites, nitrates, temp, pH)? Please give exact values.
A: Haven't measured those today. Usually nitrates tend to be higher than preferred but all has been fine until I bought the new fish.
3~ How large is the tank? How long has the tank been set up?
A: 90G tank. I've had it for 5-6 years( bought it 2nd hand - cycled).
4~What type of filtration are you using? Please give the name and number (i.e. Fluval 304) and amount of gph if known.
A: 2 filters - Eheim Pro 2 and Eheim Classic 2217(if I remember correctly)
5~How many fish are in the tank? What kinds of fish are they and what are their current sizes?
A: 20+ fish. Mostly tetras and some rainbows - most of them fully grown - except for the new ones. I also have 3 clown loaches (2-3" in length) and recently picked up some kribs.
6~When is the last time you did a water change and vacuum the gravel? How often do you do this? How much water do you remove at a time?
A: I did a water change today. I usually do 50% water changes/2 weeks Rarely vac the gravel as I have plants on the bottom.
7~How long have you had the fish? If the fish is new, how did you acclimate it/them?
A: All the fish that have died, are acting weird, or show symptoms of disease were bought on December 26, 2016. To acclimate them, I just let them float in their bags in the tank for about 20 mins as I do with all new fish I buy.
8~Have you added anything new to the tank--decor, new dechlorinator, new substrate, etc.?
Added a bit of new substrate in November 2016 on the surface to make up for the substrate that had turned to sand over time. I add Seachem Prime every time I do a water change. I've had no problems with my fish before I bought the ones on December 26th.
9~What kind of food have you been feeding your fish, have you changed their diet recently?
Flakes and very rarely dried tubifex (roughly 1/2 weeks, 1/week over the festive period)
Let me add some more detail. I've currently lowered the temperature to 23-24C as I read that Columnaris doesn't do well in temps <25C. This was done to stop a potential outbreak, if the white mouth on the rummynose is indeed that. I also read a lot of posts on people suggesting salt and others saying it's no good but I haven't tried it because I don't want to stress them out unnecessarily and potentially harm my scaleless fish. Also notice the bloated small bosemani at the beginning of the video - do you think it might be dropsy(there are no raised scales) ? Would you suggest epsom salt for that?
Here's the video I made.
Thanks
