Question Pleco loosing colour??


Does anyone know what the source of all the discolouration on his side could be? It is spreading and now covers both sides from his head down through his tail. He has no red veining anywhere but has spikes/upturned scales in a line down his side. I have added aquarium salt to his tank as per the suggestion of another member and am waiting on his response to this. Has anyone encountered this before? His behaviour is fine; active, eating, and generally quite happy. His 20G tank is cycling and the stats are .25ppm of ammonia, 0.00 nitrite, 0.00 nitrate and the pleco is alone in the tank. The discolouration is quite a but lighter than the picture shows.

Stop the salt. Do a 30 percent water change now if you could. The amonia is what is causeing it. He is getting stressed out. What size of a tank do you have?

Agree with mollies. Do not put salt in freshwater aquaria with sensitive fish (most acidic water fish are sensitive to salt, livebearers are basically not). There was a thread a couple weeks back about a pleco whose scales were literally burned off from salt. Do a major partial water change to lessen the salt, every day is fine.

There are plants in this tank, so I wouldn't expect ammonia. Do you have ammonia in your tap water? If you haven't tested it, test it straight out of the tap (no water conditioner). That may be the source.

I am treating with freshwater aquarium salt as it would be the least invasive treatment for any bacterial infection that could be starting. I added 1 dose as per the usual amount for the tank size (20G). I have been doing daily 10% water changes to ensure the ammonia levels are low due to my tap water containing chloromines. The plants are new and he is the only fish in the tank. The cloudiness is due to what I think is an algal bloom. I will be taking the tank water in to school to do some more accurate testing on the water. I purchased the pleco several weeks ago and his only real changes have been to the store and from the store to his tank. The line down his side is perfectly uniform which is why it seems strange. It nearly looks like it is supposed to be there but it only appeared the other day.

In my view the salt is doing more harm than any good it might do. Salt should never be used with such fish. Your tap water should be no worse than mine, and I have never had ammonia in the tap water. There is high chlorine and possibly chloramines (not sure, never checked with the water board) but a good water conditioner will handle that anyway.

Agree with byron. Now with that said your Tank is new! Corect me if im wrong. But your pleco looks to be a comon pleco. Which will get way to big for your tank. If its not disregard this......... Salt will burn The fish worse then ammonia. I just read a post let me find it. But it burnd the scales right off the fish. which in turn killd the fish...... Were not trying to be rude. Were just trying to prevent you from hurting your littl friend.

When I tested my tap water it tested at .25ppm for ammonia as does my pleco's tank. I know Abbotsford and Aldergrove have independent water systems as we use well water. My pleco is not a common pleco although I bought him under the impression that he was. He is a Gold Spot Pleco but will still get quite large which is why I am working on a much larger SA biotope for him

I would love to see some pictures if they are available of the pleco that was losing his scales. My pleco doesn't look like he is losing scales but rather developing very small spikes in a perfect line down his side. Perhaps that is what upturned scales looks like?? I've never seen it before....

Here's the earlier thread, there are photos but they are not too clear. Synodontis Eruptus - Flaky Peeling, or is it Cloudy Skin?

If the ammonia is in the tap water (and I understand what you're saying there, thanks) you need to address it with Prime or similar wc that detoxifies ammonia. Daily pwc won't help in this case because the ammonia keeps coming in the water.

I noticed that a few threads back I said I suspected the cloudiness was an algal bloom, I meant to write bacterial bloom, sorry if that confused anything.

It really sounds like the discolouration is due to either heightened ammonia levels or the jostling from tank to tank. Just to be clear on the progression of the discolouration, it did not get rapidly worse after the salt but progressed at the pace it was before. The salt was suggested to be added once and then wait a week so no more salt will be going into the tank.

That thread mentions some behavioural changes along with "flaking" and "ich" like spotting. My pleco has none of those things and I haven't been able to locate any online information about plecos losing their colour. He is behaving as happy and active as he always was and the discolouration is exactly that, his sides are turning grey. Oh, and I'm not sure if this helps but he is about 3.75inches in a 20G tank. That should be fine for now, eh? Byron, you mention plecos being extra sensitive as acidic water fish often are, is .25ppm high enough to cause that kind of reaction?
