Fin rot on L91?

ramblin man · Post by **ramblin man** » 22 May 2005, 20:36

I purchased the L91 on Friday just gone and today, while cleaning out the tank, I noticed the extremities of his dorsal fin was 'feather like'/split.

After only 3 days in the tank could fin rot occur, or is it more likely to be tank mates? I have noticed that he and the L114 like the same patch of bogwood. (There are more than enough hiding places for everyone - bogwood and rocks) If this is the case then one of 'em will be re-housed.

All the water parameters are nice and low (ammonia, nitrite, nitrate), but not sure of the hardness and if this could be a factor. (Just looked on the net and it's a bacterial or fungus cause disease - stress related) All other fish are fine.

All help/advise very appreciated.

It is much more likely to be fighting between tank mates. If you have other plecs they can sometimes inflict this kind of damage. I have seen it when introducing new plecs but within a week it is gone and they are getting along absolutely fine.

Thanks for the relatively good news. Will keep an eye open for them and maybe move one if it becomes too bad.

Plecos do most of their fighting in the dark, so you can catch the instigator well after the lights go off. A moonlight is helpful in this respect . . .

You say that ammonia, nitrite and nitrate are low. Can you give us the actual results please? It will help us, help you. The other tank inhabitants, how large the tank is, how long it's been set up, and how often you do what percentage of water changes are all very vital pieces of information that are requested in the sticky at the top of this forum for a reason. Thanks!

Sorry about the lack of info.

Ammonia = 0, Nitrites = 0, Nitrates = less than 20 (about 10 judging by the colour chart) The tank is well established and has been set up for over 2 years. 20% water changes at least fortnightly and sand vacuumed at least every other day.

Tanks mates are the L114 (which I think was the problem), 2x syno petricolas, RTB shark, 4x gold neon barbs.

The L91's tail and dorsal fin have recovered, so it may well have been the L114 getting annoyed with it as the L91 took a shine to 'his' piece of bog wood.

On a separate note - does anyone know for sure if the L91 has the day/night colour change? During the day he is very dark brown/black - and at night he appears stripy brown and grey.

Thanks in advanced!
