That tank is freaking awesome!

Well, she's given everyone else the opportunity to steal it from you. Btw, is anyone else wondering what on earth is going on in aviation lately? It's feels like every month there's another major tragedy in the skies!

That's odd, I normally experience the exact opposite when I add new rainbows. I'd guess he's just trying to establish his place in their hierarchy. IME the biggest rainbowfish isn't always the most dominant. Maybe the little guy is just naturally more assertive than the others.

For me it was adding too much medication and poisoning the majority of my breeding stock of rainbowfish. I had forgotten that some meds deoxygenate the water and ended up killing the rainbows. Lesson learned was not to administer meds when tired!

Try lowering the water level and then sectioning off the tank with a divider of some sort. Also, waiting until nighttime, when they're less active can also help.

Hi tetraodon, I haven't kept silver dollars, but I've kept both altifrons & brasiliensis with active fish (e.g. Rainbowfish, tetras & denisonii) without any problems. I think in a 6' tank, your geos and the silver dollars will probably ignore each other most of the time. i haven't kept...

Never been to a show or joined a local club. Part of my reluctance to join either is that all of my local shows attract mostly older, retired folk. A young son-of-a-gun like me tends to feel out of place.

Got it. Many thanks

if possible I'd also like to avoid storing the water overnight. I have a 900l tank and a 450l tank, both get water changes 2-3 times a week, depending how busy I am. I was hoping there'd be an alternative to having a container with 600 odd litres of water in my living room overnight. Boiling it...

My house has a water softener plumbed in and I'm trying to avoid using the softened water. The only taps that aren't supplied by pre-softened water only dispense cold water. Hence the need for a heater.

Does anyone use one of these? And if so, can you tell me how swiftly it heats the water? I'm thinking of buying one to heat water when I do my water changes, but it needs to be able to heat very cold water very rapidly.

Just the duckweed...I'll send a PM shortly

Hello, Any more duckweed available?

Samuel Barber - Adagio for strings. Been a long day at work so need something to chill out to.

Maybe their claims aren't so far fetched after all. There's at least one scientific paper suggesting it's possible: http://www.sciencedirect.com/science/article/pii/S0144860909000417 I haven't read the full article, but the abstract suggests it is possible to convert ammonia directly into...

This thread is a little old now, but I thought I'd post as its an interesting paper - the DNA sequencing part went straight over my head though! I was curious about a few of things. Firstly, the two samples of bacteria starter had bacteria in different substrates - one in a liquid, the other a...

I don't think you'll have much of an issue with the denisonii barbs - I have them in one of my set ups with geos of varying sizes and I'm yet to see any fin nipping or aggression at all. I think if they have a big enough group, they'll completely ignore all other fish in the tank. I currently...

There's an old thread on this on Cichlid-forum: http://www.cichlid-forum.com/phpBB/viewtopic.php?f=6&t=242062 Based on this, it looks like the device is effective in the short term, but its long term efficacy is unknown. The manufacturer claims it deals with nitrates as well as ammonia and...

I've seen mine rise and gulp air, but never noticed the farting afterwards. Maybe it's some kind of intra-group communication - apparently herring do this.... http://news.nationalgeographic.com/news/2003/11/1110_031110_herringfarts.html

I completed your questionnaire earlier, and agree with the previous posts that there are some methodological shortcomings to be addressed. For me, the biggest problem was that all of your questions presume I only have one tank. I'd be curious to know what your hypotheses are. What are you...

Thanks for the info guys, good to know I'm not imagining strange noises! Any idea why they do it?

Ok, seems I was wrong - it is a resin-based system after all. The salt is used to regenerate the filter. Strangely, the salt packet doesn't mention the ingredients at all. I did find the list here though...

Not so long ago, I had my bronze cories in a container as I was moving my tanks. As I observed them to make sure everyone was ok, I'm sure one of them make a high-pitched squeaking sound. Anyone had this before or know what triggers it?

Thanks for the info. I'm pretty sure it's not a resin based system as there's no rechargeable beads/substrate involved. It's a device that's plumbed into the mains, requiring periodic the addition of salt tablets like these: http://www.wickes.co.uk/Hydrosoft-Salt-Tablet-25kg/p/221263 I keep...

So, I've recently moved house and the new place has a water softener plumbed in. Does anyone run a set up using softened water? I was wondering if it there'd be any ill-effects on my fish if I used pure softened water, or if it's best to mix it with the regular London hard water that my fish...

Hi, I have two of these on my 4' tank. They're good filters when they work, but are incredibly frustrating when something goes wrong. Personally, I would be reluctant to buy one second hand unless I could see it working first. This is primarily because of the number of online posts people have...

Undoubtedly, death by mycobacterium isn't the most statistically frequent way for aquarists to kick the bucket, but that doesn't make it completely innocuous. For one thing, open wounds may not be the only way for it to infect a host. Here's a link to a study which investigated how one strain...

I would think that ingesting tank water can be harmful if you consume a large enough quantity. I've never cultured bacteria growing in a tank (or known anyone that's tried), but I'd assume tank water is teeming with bacteria. Even if these bacteria are not pathogenic I'd think they can still...

Many rainbowfish, Central American and African cichlids would be fine in hard water.

Thanks for the responses guys - I'll try fishing line, and if that doesn't work then suction cups

Normally people can't wait for their wood to sink, but I'd prefer to keep it floating as I think it looks better (and my fish seem to be more secure). I'm currently tying golf balls wrapped in moss to my wood. It works, but looks rubbish. Does anyone have any better ideas for keeping wood afloat?

+1 on the awesomeness of geos...also, haven't you got rainbows as well? They'll work well with geos.

They look like snail eggs to me - you'll probably experience an increase in your population very soon!

Yes, it was a fish...the trouble is you needed to specify which type of fish. It's an archer fish. I can't think of another one right now, so over to the first person to post.

I've used both API's and Interpet's (Blagdon) master kits. Neither of them made me say wow, but they were ok for what I needed. With the exception of the ammonia, Interpet's test are fairly straight forward. Interpet's nitrate test is much more consistent than API's because you don't have to...

Ok....what is this guy:

Is it geophagus tapajos?

Or, it's a minimalist tank - nothing goes in it except air.

Does the tank currently have any livestock in it? If not, you could try methylated spirits - I found it very effective at cleaning hard water marks on my latest tank.

I'm sure our dear friends in Westminster will think of some way to tax it....and then misspend it!
