Your current Fish tank Setups!

what are your temperatures like? Due to the warm weather your water temp might have increased, and IIRC warmer water holds less oxygen. Just a guess - might be worth sticking an airstone in if you don't already have one?

Good call, I hadn't thought of that. But alas it's 27.6 degrees as usual, digitally measured with a probe at the bottom of the heater end of the aquarium. They're all still eating and no clamped fins etc, just breathing faster than normal and (as I said) the glowlights are hugging the surface. I've changed the outflow of the (external) filter to agitate the surface more and I'll grab an airstone this afternoon to help them out, but I do think it's a case of pH shock unfortunately. Going from 6.2/6.4 to 7.8 overnight is a huge jump. :(
 
To swing the PH that much in a single water change the water must have been rock hard, but its likely just PH shock. You also have to remember that PH is logarithmic so that really is a huge swing.
 
Yeah exactly. They seem to have settled a little this evening. Still occasionally popping to the top for a gasp but otherwise fairly settled and swimming more normally (and at their usual depths). They're still eating as well, so fingers crossed they'll adjust OK.
 
Damn idiot rasbora, one managed to get itself stuck in the filter, fortunately we noticed and managed to free it.
 
Indeed contrary to popular belief BN Pleco do nom nom plants, especially large flat leaves like you get on swords.

As course as with all fish your results may vary.
 
I'm soon going to be in a position to stock my 95l tank. First time tropical for me after years and years of keeping cold water fish (still am, just in a pond now)

I was going to convert my old 60 litre tank but the chance to get a new tank presented itself!

So here I am patiently waiting for the cycle to finish.

I'm not one for having 1 or 2 of lots of species so I would like to keep a shoal of 12-16 black neons, 6-8 otocinclus and later in the year add a pair of Bolivian or Blue rams.

Does that stock level sound about right? Could I up the neons?

Tank will be planted using tropical aqua soil substrate.
 
Not having much luck with our fish :(

Came down this morning to find our Lemonpeel dead, stuck up against the weir, completely unexpected, she was swimming around fine yesterday, so no idea what happened, no damage to her so doesn't look like she was attacked, all of the other fish are fine, corals are happy, water params haven't changed, not changed routine at all... Gutted, was a beautiful (and expensive!) fish :(

Low dissolved oxygen due to the heat maybe? Have you noticed any fish yawning/flicking/rubbing? Could be that they have gill flukes or some other parasite that is reducing the efficiency of their gills. Only other thing that should be able to kill that quick is a bacterial infection with no outward symptoms.
 
All the others are acting completely normal, swimming about quite happily, no unusual behaviour, we have decent surface agitation plus the skimmer, and the temperature is no higher than it has been for the last month, hopefully not an infection, we haven't added anything new to the tank for a couple of months :/
 
It can also be just one of those things - Fish like all animals just randomly die sometimes I guess :/. The guy in my LFS told me that one time he went to scrape the glass on one of their sale tanks and a pair of expensive angels just keeled over immediately. They'd been healthy at the shop for weeks...
 
I wonder if anyone can shed some light.

I recently bought a small tank (46L) for small fish. I was going to post some pics once everything had settled.

I've had the tank with live plants for about 4-5 weeks now and it has had Cardinal Tetras for around 2 weeks now (13 of them). So far eveything was going great. They were getting used to their new home and are feeding well.

3 days ago I decided to add 3 platies to the tank (it's as far as I am going for this tank size). The first 2 days they were hiding away, which was to be expected, but they would not feed. Day 3, they finally turned up during feeding, and they would generally hang near the top of the tank, while the cardinals were at the bottom. Both types of fish don't seem to be bothered by each other, which goes with what everyone has said about them being good community fish.

Now, last night I was watching tv and at the corner of my eye, saw one of the cardinals floating/swimming erratically to the surface, then just stopped moving. I look a closer look, and it looks like its tail is totally missing! Poor bugger was still alive at this point. Moved it into a smaller tank incase there was something wrong with it. Roll on an hour later, the exact same thing happened to a second cardinal! This time, only half of its tail missing, but remained motionless like the first.

My first thought was the platies nipping at their tails? Just seems a bit odd that this happens shortly after adding one of the so called friendliest fish to the tank.

Anyone had similar issues before? Is it just platies thinking the cardinals tails are food? Or is there possibly something else going on?

I didn't have time last night to do a proper water test, but I did use the api strips and everything was coming back as ok. Water is sitting at 26c if that helps.

Platties, like many livebearers, are semi-aggressive fish. Especially in low numbers (under ~10) of their own kind and in tanks under ~120cm long.

I'm not surprised your Cardinal Tetras are being attacked, your setup contradict both issues above.

Very few species are suitable for compact, small volume tanks. I wouldn't put Cardinal Tetras in a tank with its length under 90cm and Platties, at least 120cm.

Get an ICP test done, could be many factors but you will know what's in the water this way.

Cheers for the reply. Just annoys me when you are told by the people who sell you the fish it would be fine.

Not sure what to do now.

I am going to be moving my 2 gold fish from their 72l tank into a 200l tank at the end of the month, so perhaps I could rehome them in that?
