Seems reasonable ... more surface material, more potential food for the larvae. I'm trying to rapidly upskill myself in this area so I don't lose any more fish ... providing citations so I can check back on these threads later on. If this is against board etiquette I didn't know.

As these are new fish you need to keep them quarantined. Since some have got sick and others haven't, I would suspect a bacterial infection. Some sites suggest adding tonic salt in the correct amounts slowly over the next couple of days. And if no improvement, Sulphonamides.

Are you sure that your tank is still not cycling? You don't mention nitrite levels. And got a picture?

This might be the same fish last week when I still had my neighbour's camera Hard to tell since they look much the same to my untutored eye.

Sure .... take it out after 6 weeks and replace if you want. Like any material the carbon will become a bacterial filter as it loses its absorption abilities.

I'd like to see a reference to support that statement. This link http://physicsworld.com/cws/article/news/30558 says mosquito feet can repel water with a force of 600 µN – roughly 23 times the mosquito's body weight – before breaking the surface. So, using another surface to land on seems redundant.

http://www.hallman.org/filter/gac.html So, in practice and experimentally, no, it won't release toxins back into the water.

Interesting .. I don't recall seeing egg rafts .. will have to look harder. Is it Culex quinquefasciatus ? And what do you feed the larvae on? Algae?

Yes, they're all fancy goldfish apart from the 2 comets. A neighbour has a goldfish pond ... perhaps I can slip them into there one night :gigl: I had the black moors in their own tank as I read that their poor eye sight prevents them competing for food against the normal eyed fish, but have watched them carefully and they seem to be able to get a fair share. The comets don't seem to be eating more than any other goldfish.

Ammonia reader rated for a year, and only a month old. Checked against the API test kit and correlates. Just wondering if I needed to do anything for the other fish like add tonic salt ... some sites say it's an old treatment and not necessary. I do have a canister filter rated for 2000L/hour but I thought I would freak out the wife if I installed that in the kitchen so it's in storage in Napier I got the box filter as it is much quieter than an air stone, and the HOB water output runs against some craft canvas to stop the water fall noise which was disturbing her while cooking Goldfish - 2 comets, 2 calicos and 1 Oranda .. all quite young ( ooops .. forgot about the 2 black moors ) I will move the goldfish to a larger tank when they get bigger!

Found one of my WCMM floating in the tank this morning when I was about to do my bi-weekly partial water change just before leaving for work. Been a week since I did a census so I can't be absolutely sure this did not happen earlier. Ammonia is 0 according to the seachem sensor stuck inside the tank ( 180L, 6 other WCMM sourced a month ago, and 5 goldfish ). Running 3 filters ( an internal one to give a little current for the WCMM, and an Aquaclear 50 HOB, and a box filter. Fins, eyes, and coat look good, but abdomen looks quite distended. Ascites? Did a 25% water change and wondering if I need to do anything else .... other tank mates seem fine in the short time I had to scan them.

I think youre right... it's just a hole with a shaped cone to plug the air hose to it ...

So, I wonder what this guy who is moving to Oz is going to do with all his corals if he can't sell them? I guess the nearest LFS that has marine stock would be in Hastings ....

Sounds like a long term project fraught with danger!

It's actually worse than that ...I have another 10L tank that I can use for a hospital tank though it was originally intended for some experimentation, another 170L tank that is sitting in storage in my new office,and I am about to commission a much larger tank for my office. So, a more accurate description would be Rapid Onset and Progressive Multi-Tank Syndrome ( ROPMTS ) :sml1:

Ahh..helpful. And he says he has a skimmer but is not using it.

Must be the season for it. On page 2 of the Wgton CityLife (Jan 18). there's a story of someone who saw one of these Australian moths opodiphthera eucalypti ( beating against his bathroom window ) on Christmas Eve. This one had a wingspan of 12 cm. Says that they only live for 2 weeks.

I started with my first goldfish in October. After losing a couple, I decided I needed to learn a bit more before I killed anymore! :smln: So, anything I say has to be taken with a grain of tonic salt.

Since you don't know what the toxins were ... I would be worried it might be adhering to the silicone. So, I'd wash it out completely a few times, and then recycle the tank, and see if some pond snails proliferate in it.

I've got 4 tanks in use at present ranging from 180L to 30L with goldfish and WCMM, then blue gourami + fancy guppies + BN babies, then another with juvenile angelfish that I need to move to a larger tank soon, and then a few Betta splendens which I picked up this week from another member here ....

Just curious as to how much work would be required this tank being sold on TM? http://www.trademe.co.nz/pets-animals/fish/fish-tanks-aquariums/auction-440175850.htm I would have access to FSW across the road ...

I tested it on Chrome

Looks like it could feed a few fish!

Some rubber used for sealing against water ingress is impregnated with an algal inhibitor which is highly toxic to fish.
