David R Posted July 31, 2016 Report Share Posted July 31, 2016 I noticed this on my second largest L190's tail a few months ago, it hasn't seemed to have gotten any worse (or better) and the fish otherwise seems healthy and normal. Cancer? Warts? Any other suggestions?The fish is about 12", it's in my 2000L tank with three other large L190 and a bunch of other fish, water is 26-7C, pH ~6.8-7, <10ppm Nitrate, <70ppm TDS. Sorry the cellphone pics aren't the best, I can get out the DSLR if better pics would help... Quote Link to comment Share on other sites More sharing options...
livingart Posted July 31, 2016 Report Share Posted July 31, 2016 (edited) Scar tissue?Does it fan its tail out? Edited July 31, 2016 by livingart Quote Link to comment Share on other sites More sharing options...
David R Posted August 1, 2016 Author Report Share Posted August 1, 2016 I'm certain the tail seems to work normally still, but I'll spend some time in front of the tank after feeding tonight to make sure. The big Panaques do have the occasional tussle but the pecking order is pretty well sorted so it's never too serious, it's shape and distribution looks unusual for scar tissue.

hovmoller Posted August 1, 2016 Report Share Posted August 1, 2016 Have you considered catching it and dabbing the growths with some wunder tonic? Just to see if it would help.I suppose that couldn't hurt. The biggest problem might be to catch it. Quote Link to comment Share on other sites More sharing options...
Caryl Posted August 1, 2016 Report Share Posted August 1, 2016 It isn't secondary fungal infection over old wounds is it? Looks like a bit on the fin too? I have seen similar and when caught, the fluff could easily be removed to find a healed wound underneath. Quote Link to comment Share on other sites More sharing options...
David R Posted August 1, 2016 Author Report Share Posted August 1, 2016 Thomas that is exactly what Shane on Planet Catfish suggested, although he said methylene blue. I'm guessing the additional ingredients in the Wunder Tonic won't do any harm. Does that stuff go off? I've got some but it's a good 6-7 years old!Caryl it's not like any fungal infection I've seen before, certainly not fluffy, looks more like some sort of hard gristle sort of stuff coming out from under the skin.I guess I'll have to set aside an afternoon and dismantle the tank to catch it. I've been thinking about doing that anyway to check on the progress of the L85's and to have a bit of a rearrange/rescape and add in some more rocks, so it's probably a good opportunity to do both!

Ira Posted August 1, 2016 Report Share Posted August 1, 2016 Lymphocystis, maybe? http://edis.ifas.ufl.edu/fa181 If that's what it is, there are heaps of strains, but looks like mostly there's no treatment but it's not general fatal and usually clears up in a few months.

alexyay Posted August 2, 2016 Report Share Posted August 2, 2016 (edited) I'd lean towards "you can't really do anything about it", sorry Either Viral, or tumours/cysts. Do they ever disappear, or "burst"? If you feel you can apply a medication (eg Wunder Tonic, which should be fine) directly to it without a huge amount of stress, it's always worth a shot. But unfortunately I'd vote virus (whether it be Lymphocystis or another - not really worth getting an exact diagnosis as there's nothing you can really do about it anyway). I personally don't usually isolate fish with viruses as they're always kinda present, but it's worth noting that fish are more likely to become infected if they pick at it and when it eventually passes away (as is inevitable with any living creature lol), you'll want to remove it asap as other fish will definitely have a nibble. Edit: I wouldn't suggest doing it by yourself, but if a vet wants to help you anesthetize the fish and get a small sample, it should be fairly easy to diagnose under a microscope (the cells will look huge - below is a virus from one of my fish, not a great picture sorry). If it passes and you know someone with a microscope, they won't degenerate (ime) when frozen, so you can, err, keep some in a freezer for future diagnosis).

David R Posted August 2, 2016 Author Report Share Posted August 2, 2016 Well I've spent the afternoon collecting, scrubbing and soaking rocks and I'm going to do a bit of a stocktake and rescape tonight, so I may as well fish him out and dab some tonic on it. Nothing ventured nothing gained! I could nick a tiny piece off with a new razor blade and freeze it to examine, but I don't know of anyone with a microscope unfortunately.

David R Posted August 2, 2016 Author Report Share Posted August 2, 2016 All done, no dramas, looks good but needs a heap of smaller rocks to finish the look. Caryl, Adrienne and JJWooble 3 Quote Link to comment Share on other sites More sharing options...
hovmoller Posted August 3, 2016 Report Share Posted August 3, 2016 Looks good! Plec allright? Quote Link to comment Share on other sites More sharing options...
David R Posted August 3, 2016 Author Report Share Posted August 3, 2016 Yeah seems to be, no change in the lumps yet though. Tank is still a little cloudy but I'm happy with how it's looking. Good chance check up on how the nuggets are doing, I wish I saw them more often as the bigger ones (~6" now) are very cool!

hovmoller Posted August 3, 2016 Report Share Posted August 3, 2016 Nice! I suspect the geos will make sure all those rocks are lying bare on the glass in no time, hehe. Quote Link to comment Share on other sites More sharing options...
David R Posted August 4, 2016 Author Report Share Posted August 4, 2016 They're nestled right down into the sand, but it will be interesting to see how much they dig around them. The return fromt he sump pushes a fair current through the wood pile and tends to move the substrate out of that corner anyway. Quote Link to comment Share on other sites More sharing options...
Tim M Posted April 24, 2021 Report Share Posted April 24, 2021 Hi David, I know this post is nearly 5 years old now but I’ve got the exact same thing showing up on my L190 and was wondering what the outcome was with your fish and if you found out what it was? Would really appreciate any advice. Thanks Quote Link to comment Share on other sites More sharing options...
