This is all the info I have so please be patient with my lack of it. Sorry. I have no decent test kits. I live in the middle of nowhere.

About three weeks ago, I rescued a betta. He was absolutely traumatised like the last betta I rescued from that dump. The plan was keep him quiet, rehabilitate him like the last one, maybe even breed him. But I couldn't get him to eat. He took a few mosquito larvae in a fortnight. He was already far too skinny - well he was ending up emaciated.

I thought he might be more willing to eat - or at least show interest in something - if I put him with a female. So I put them both in a cycled, filtered 6 gallon tank, him loose and she in a glass chimney. I thought I'd let her out and spawn them if she egged up and he blew a nest but no plans to do it immediately as they weren't conditioned. He did perk up a bit and start eating so I figured it was best to leave him like that. He stayed there for about a week. Still no plans to release the female.

I sorta figured the female might be getting sick of sitting in a glass chimney in the middle of a tank, so I thought that since he'd perked up I'd shift her. She went back in her own tank, 1 gal. He stayed where he was. The next day I noticed him sitting on the bottom and getting lethargic. That was Wednesday. I added a piece of wood to block the current in case that was bothering him now the chimney was gone. I came home from school and realised that he was seriously sick. I took a closer look and saw what appeared to be fungus - yellow and fuzzy - on his side and growing on the base of his tail, more on the body than the fin. I freaked out. The only antifungal I had was crap - malachite green, methylene blue and acriflavine - but I used it anyway. I took him to school the next day. One of my teachers breeds them. She didn't know what to do, suggested bettafix and basically said 'he's cactus'. I took him to the LFS. No bettafix there. They couldn't suggest anything, said they'd never seen anything like it. They had a heap of new fish in and I couldn't resist a 4 ray CT male. If the betta that was sick had been from a divided tank or a community I would never have considered buying another fish but because he was going in a separate tank I thought everything would be okay.

Later that night the rescued fish sank really fast. The fungus doubled in area and he was lying on his side gasping. I decided it was cruel to leave him and put him down. I also noticed that my breeding prospect I'd had for months was looking majorly, majorly sick. I thought he was a fish TB carrier and I'd been keeping him alive because he was an old friend basically, he had the tank to himself so I sorta figured 'what harm could it do'. He went the same way, once he went down he was gone within 12 hours. No sign of any fungusy stuff but it was the same at the end, lying on his side gasping.

Well tonight the female I'd had in with the rescued male got sick. She was fine last night. Looked upset this morning but I thought she didn't like the filter. I turned it off. Tonight i went in to feed them and she's lying on the bottom, covered in yellow grot on her side and gasping. I had to put her down as well.

To make matters worse the new CT's not eating. I'm scared I might accidentally have contaminated his tank with something I've used in one of the others. I just can't remember. He could just be having a rough time settling in or just be a nervous temperament. I have no idea. I'm scared off my brain though. I've had most of my bettas for months, trouble free. To lose three of them in the space of a few days has totally freaked me out.



Of anything it most resembles columnaris what with the covering the body and very, very rapid deaths. But I dont' think it is somehow. The water is too cool for columnaris, but not so cool the fish would be stressed (23-24C). The lesions start on the belly, not the back and there is nothing out of sorts at all around the mouth or face. It's not white and it doesn't form long strands, just fuzziness a few mms thick all around the body in the affected areas. I'll try for some photos of the female. It also causes total loss of colour in the scales wherever it goes. The female is normally dark greenish blue. Make that was.

It's no good asking for decent water stats because I dont' have accurate kits. All of the tanks I used were cycled, 25-40% water changes done weekly, more often if the fish are being fed heavily (ie conditioning to spawn.)

Just please help me, anybody if you recognise this!
 
Could it be getting in through untreated channel water? Should I add bleach to the water and then treat it with dechlor before using it? If so how much bleach?

EDIT: The white spots on her face in the second photo are reflections of the flash of drops of clove oil in the water. Sorry.

Sorry laura thought you was replying to a member.
R.I.P.
Did the fish put weight on with giving it good meals.
Being skinny can be old age, not eating, fish tb to internal parasites.
Yes yellow fluffy bits is columnaris it comes in many colour, white, greyish white, yellow, pink and brown.
Columnaris can also affect the gills.

I would say bacterial, especially if your water supply is untreated channel water. Here's a little link I found on treating rain water for domestic use, and how much bleach to add to disinfect; http://www.tceq.state.tx.us/files/gi-366.pdf_4231966.pdf

I add 2-3 drops of bleach to my bbs hatchery, about 1 1/2l of water. It smells like a swimming pool when I set it up, it gasses out in 24 hours with heavy aeration.
 
Thanks guys! I found another treasure trove last night, some spring water (filtered and pure) that we went camping with and didn't drink because our friends had some open. I have about ten litres of it, so my bettas will be in very small containers for a while but it's better than being exposed to this. I'll be able to start treating water for them too... only problem is that we only have lemon scented bleach. If I use chlorine neutraliser will it be okay? It's in form of sodium hypochlorite, sodium won't hurt them.

So it is columnaris? It's the most virulent strain of it I've ever seen. I'm seriously considering breaking one of my usually strict fish rules and treating the new fish that's not eating with tetracycline just in case he's been exposed. Any advice either way?

The female was skinny when I got her but only because there were bigger fish (aggressive platies and swordtails) in the same tank, as soon as I fed her properly she started to put on weight and egg up. Hard to know with the rescue male because he didn't get proper meals, he hardly ate anything I offered him (Hikari bio-gold - not like i was trying to feed him crap.)

The gills of the two that went fuzzy were brick red and inflamed before they died. I don't know how bad it would have gotten, when they were lying on their sides unable to move and obviously in some distress I had to put them down. I knew I couldn't save them and I can't leave animals suffer. The other male was fairly old (more than a year) and I think he had fish TB. I've treated him for internal infections before, but they only live so long even with aggressive treatment of secondary infections. I think it was just his time, he'd been less active and had less appetite lately. He had a good life with me anyway, TB or no TB. Just my luck he'd die at the same time - the same reason the half gal aqua garden split and ruined a chipboard shelf yesterday and a fish that's been nowhere near any of the infected fish or water has dropsy. (He's recovering very well, I caught it early before his scales pineconed.)

I am curious though - apparently Maracyn 1 which is effective against gram positive bacteria kills columnaris. Description from wilder's link: (Description: Gram- Negative Rod Bacteria)
I do have tetracycline though and I've saved columnarised fish from that before, although admittedly a much less virulent strain.




"Antibiotic resistance is a problem facing aquarists all over the world. This occurs when bacteria evolve to make newer, stronger strains that cannot be combated by available antibiotics. Flavobacterium columnare is an example of such a transitioning bacteria. There are several strains of flex from the mild to severe and recent accounts of a particularly virulent strain have made its way into aquariums. These newer strains have been known to kill fish in under a day and may be untreatable. To avoid creating tougher strains of bacteria be sure to carefully follow the directions on the medicine package and to never stop or change medications part way through treatment unless your betta is having a dangerous reaction to them. As with any disease, remove your sick fish from the community tank and isolate him for treatment in a hospital tank. Never medicate healthy fish."


Oh crap. The golden staph of the fish world. If this is columnaris it kills from 18 hours of appearance of first symptoms. Just what I need huh?
 
With columnaris you are better using maracyn one and two to cover all bases.
How are the fish now laura.
 
I wouldn't use any bleach that has any kind of scent to it. Get some pure stuff.

I really hope you get this all straightened out and your new CT doesn't go down the same way.
 
Too late, he's dead. I'm bleaching everything, then I'm going to soak it in chlorine neutraliser and leave it dry for a few weeks, then rinse it and restart. This is absolutely awful. Columnaris that kills healthy fish.
