RichardCichlid Posted December 11, 2014 Report Share Posted December 11, 2014 .So still following the aftermath of a week away, the other juvie Albino oscar seems to be getting sick. He has began to lie on his side on top of the internal filter. The first juvie albino oscar I came home to nearly dead has been separated and in a separate tank and is recovering and thriving - http://www.qldaf.com/forums/help-fish-health-diseases-water-quality-12/injured-oscar-help-please-again-116394/ (while I was gonna the third little albino had jumped). Family was looking after them while I was gone. I got these three from the same store and had no problems for a couple of weeks by themselves. Then from the same store but two weeks after I got a normal tiger oscar of the same size. All four were fine all together for a few weeks, with the normal tiger asserting himself as leader but nothing overly aggressive. Then I left for a week and came home to what is described above ^ What happened?! Now the last healthy albino is looking sick, and I need help. What do I do? I put Melafix and aquarium salt in immediately when I saw his sores, which are on both sides. Link to comment Share on other sites More sharing options...
Daharkazangel Posted December 11, 2014 Report Share Posted December 11, 2014 Gills look like ammonia burn, your readings ok?? Link to comment Share on other sites More sharing options...
RichardCichlid Posted December 11, 2014 Author Report Share Posted December 11, 2014 Looks like a weak 0.25 - Ammonia, 0 - Nitrite, and waiting the five minutes for Nitrate. Surprised to see some Ammonia, I took the internal filter straight from the big tank where it's been running for ages, gave it a clean in tank water, and had been running for a month now fine.

none Posted December 11, 2014 Report Share Posted December 11, 2014 Oscars are sooks. Is your water temp excessively high? Are you sure the newer Oscar isn't asserting itself more than you've noticed? Do you ahve hiding spots in the tank? The gills do not look good. Are the fish gasping in the tank?

lgw Posted December 11, 2014 Report Share Posted December 11, 2014 What size tank, how many fish and what filtration/media are you using? Link to comment Share on other sites More sharing options...
RichardCichlid Posted December 11, 2014 Author Report Share Posted December 11, 2014 No, actually just turned it down from 28 to 26, getting a digital thermometer on the weekend though, as the ambient air temperature was getting up to 30 degrees. Not sure about before, but now with two left in the tank they are like best buddies, swimming next to eachother. I've got one piece of driftwood in, but that's probably not enough, good idea. And no, not gasping at all, surface water movement is great and there is an airstone bubbling away also.

lgw Posted December 11, 2014 Report Share Posted December 11, 2014 And have you changed water and forgot to use a dechlorinator? Link to comment Share on other sites More sharing options...
RichardCichlid Posted December 11, 2014 Author Report Share Posted December 11, 2014 They are about 6cm so they are in 40L small tank. It's just the two oscars of the same size and I am using an internal filter of 250-500L/h with foam and matrix [MENTION=6895]lgw[/MENTION] I doubt it, I always use prime and it's in a visible spot too, so I always see it when I do the waterchanges.

And no, not gasping at all, surface water movement is great and there is an airstone bubbling away also. Thanks for the replies @none and @Daharkazangel Darken the tank for a few days. Oscars respond very well to salt. I would do a water change (if you haven't already), add salt and just monitor them for a few days. Gill Flukes can cause gills to get damaged but the treatments are very harsh and I wouldn't want to treat without knowing it's definately flukes. Furthermore flukes are naturally occuring and getting the water under control leads to improvement in itself. Just monitor them - looks for the obvious - white spot - and see how the go. Imported Oscars are often full of disease. By the time they get to the retailers tanks they often haven't been fed much for a month or two so that is a major stressor in itself.

lgw Posted December 11, 2014 Report Share Posted December 11, 2014 With the recent weather they may have added more chlorine to the water (if you're using town water), so it may be worth double dosing after heavy rain. I'm sure you're aware but I'll say it anyway, those oscars will grow rapidly and produce a lot of waste, they'll need a big upgrade shortly!

Daharkazangel Posted December 11, 2014 Report Share Posted December 11, 2014 Yeah 40l for two, no matter the size, is crazy small. In a tank of that size, any ammonia can cause damage. They grow a inch a month O_o Link to comment Share on other sites More sharing options...
RichardCichlid Posted December 12, 2014 Author Report Share Posted December 12, 2014 I've got a 5x2x2 for them to go in, then next year because I think they look better with more space they will be going in an 8x2x2. Thanks for the replies everyone, never good seeing your little fish sick. Link to comment Share on other sites More sharing options...
lgw Posted December 12, 2014 Report Share Posted December 12, 2014 They certainly do better with more space, I had a 7'x20"x20" for my 2 and they used every inch of it. I miss my oscars, I'll definitely own them again one day. My favourite fish by a long shot. Link to comment Share on other sites More sharing options...
