Re: Recommended salt concentration #1
OK - will do! The packet states 1 teaspoon per 5 litres on the first day which is then increased to 2 teaspones per 5 litres on day two. Also do daily water changes.

This sounds a bit OTT to me. First of all, Interpet Treatment No 9 states not to do any water changes until 7 days after the last dosage has been added. Secondly, if my calculations are correct I'll end up with water that contains more salt than seawater which, surely, isn't good for fresh water fish!

I'm dropping by my LFS this afternoon to have a chat and see what they recommend.

Thanks again for all your feedback - it has been enlightening! LOL

All the best,

Dan

Re: Recommended salt concentration #2
I had another looooooong look at him this evening, which is easier said than done seeing as he's very quick, and it would appear that he's got a few scales sticking out. Not all his scales just a few.

So tonight I have started a new course of No. 9 "internal bacteria" (incl. dropsy) treatment ... I hope it is not too late but I guess the next couple of weeks will tell.

Unfortunately I do not have a separate tank available to isolate him and treat him separately ... I'm very hopeful/confident the Santa will bring me a small hospital tank in a few weeks time

Question - as I am now medicating, does anyone know what concentration salt the water should be? I've also heard that raising the temperature a couple of degrees could aid the fish with recovery (current temp is 24.4C).

Many thanks again for everyone's feedback!

Good night!

Dan

Re: Recommended salt concentration #3
Hi Coralline - thanks for your feedback.

At the moment there should be next to no salt at all in the water as I ran out of tonic salt about 4 months ago and have continued to do upto 20% water changes every 2 weeks.

The Danio started getting fatter about two weeks ago following a tank treatment for internal bacteria. The treatment cured one of the rummy-nose tetras who was displaying swimbladder problems.

He's not getting bigger in just one area, ie his belly, he's getting bigger all over! The strange thing is that some days I swear I can see his scales sticking out but then I look again the following day and his scales are perfectly normal.

It's really a mysterious condition to say the least.

I was told by my LFS (Sweet Knowle Aquatics just outside Stratford upon Avon) that the aquarium should have a low level of salt in the water to ensure proper osmosis (for fluid balance). When treating illnesses the concentration should be increased (gradually of course) and then decreased to normal levels.

I'm not suggesting that I want to creat a brackish environment, just maintain the proper level of salt in the system

Thanks again for your feedback - much appreciated!

Dan

Recommended salt concentration #4
'Ello all!

I haven't been on here for ages - nice to be back!

Question: what is the recommended salt concentration for a 55L tropical community tank? The tank is currently stocked with a variety of zebra danios, rummy-nose tetras, cardinal tetras, two clown plecos and two zebra snails.

Reason I ask is that I have noticed one of my Danios becoming increasingly obese (if that is possible in fish ...) He eats his share of the food, deficates properly and seems generally happy but he's getting fatter with each passing day! I'm afraid he might pop soon ... As I don't think he's gorging himself there may be a problem with his chemical balance and he's retaining water. So I thought I'd get the salt concentration right and see what that does. I do add a small quantity of salt with each water change but it is not a scientifically determined amount - just a small amount so that there is some salt in the tank.

So any and all recommendations are gratefully received!

All the best!

Dan

Re: disease diagnosis requested #5
Nothing that I can see. Have no silly plastic ornaments in the tank - it's all natural, ie plants, rocks and small piece of bogwood (favourite hiding place of my clown plecs!) And there are no external abrasions or damaged scales either ...

Could this possibly be a secondary infection due to stress? I've seen the four danios chasing each other quite relentlessly this past weekend, but then again they often do that.

So far none of the other fish are showing any symptoms or signs of there being anything wrong.

The mystery continues ...

Thanks!

Dan

Re: disease diagnosis requested #6
Water is very clear - only things that occassionally float around is flaked food (but not for long as all my fish seem to be hollow and always hungry! )

Not sure if those gill parasites are visible to the naked eye but (without doing a full post-mortem) I could not see anything untoward inside either gill. Flukes would also make the fish "flick" on the substrate and rocks, wouldn't it?

Am still baffled this has happened so quickly ...

Thanks for your feedback - much appreciated.

Re: disease diagnosis requested #7
Sure - no problem.

Readings taken just after 5pm today:

Tank: 55L/hexagonal/Internal Interpet PF2 filter/gravel substrate/approximately 2.5 years since cycled

Temp: 24.2 degrees C
pH: 7.29
NO2: 0.01
NO3: 5.0
NH3: 0.0
KH: 5 (german)
GH: 11 (german)
O2: 8mg/l (which is above 75% of recommended saturation)

The only reading which is too high is PO: 5+ (trying to control with weekly 20% water changes) However, tap water has high PO reading also.

Regards,

Dan

disease diagnosis requested #8
Hi all,

Haven't been on here for quite some time - busy with work and a happy tank.

One of my zebra danios has just passed away after what appears to be a very short illness.

At around 8 o'clock this morning (= feeding time) I saw him sitting on the substrate wedged between a moss ball and a plant. Didn't think much of it as he came up to feed. An hour later he was once again at the bottom of the tank sitting on the substrate. Thought I'd better keep an eye on him.

Went about my daily business and at around 1pm had another look. This time he was floating (right side up) at the top not doing much of anything, just trying to stay out of the way of the current. Again, not sure what was going on and put it down to the fish having an "off-day" - these things happen.

Then at about 5pm I found him floating upside down in the tank, dead

Immediately fished him out and upon close inspection I found one of the gills to have secreted a sticky puss-like substance. This to me sounds like an infection of some kind but this certainly wasn't visible when I last looked at him around 3pm (still at the top, right side up). Everything else about the fish (appearance, texture, etc) is perfectly normal.

This has really baffled me and I am now unsure what course of action to take. I would like to medicate the tank in case it's a waterborne disease but I don't know what it is and hence can't medicate for it.

Water tests reveal perfect conditions and I haven't added any fish, snails or plants in the past 4 months.

If anyone has a thought about what this could have been I'd be very grateful for the information.

Thanks for taking the time to read this.

All the best,

Dan

Re: Apple snail shell regeneration question #9
Thanks for your feedback - much appreciated.

The temperature in the tank fluctuates between 23.6 and 24.2 degrees C (depending on the time of day) so I suspect he'll heal over time. It looks awful at the moment and I was quite concerned to feel how soft the bit underneath the missing shell was. If I get the chance I'll put up a pic later today/tomorrow.

All the best!

Dan

Apple snail shell regeneration question #10
Hello one and all!

Haven't been on here for ages - nice to be back!

All is still well with my tank - no additions and thankfully no deaths either.

I've just been away for three weeks and upon my return found Goblin (my golden apple snail) to be missing a chunk of his shell near the rim. I can only guess that he landed a bit unfortunately on one of the rocks. I've examined him closely and where the shell is missing there is soft tissue. Well, I say soft but that's only in comparison to the hard shell. I think the tissue has a tough outer layer to it. The snail seems to be perfectly happy and still performs his daily acrobatics (climbing to the top and floating down on his foot ... )

Does anyone know if the missing shell will eventually be regenerated?

Cheerio!

Dan
