Is it a tubeless design?

Perhaps he can start with a krill marine tank? That would keep the costs down!

Who's paying for it! :slfg:

Congratulations ... you're on your way. Now to slowly add some more fish.

chocolate fish?

I think you need an IQ higher than 100 to provide the volume of a tank unless you've keep the wrapping. And the number of people who advertise their tanks with no measurements ( can't find ruler ), or pictures ( sorry, camera is broken ) ... and those that can't measure the glass thickness ... It would be best TM had a template for tanks as they do for houses; that's what I would push for. And the volume appears in the advert title.

It probably applies more when you have sand as a substrate as all the crud then settles in the dead spots and so you don't have to clean the whole tank, just the dead spots. Removing that stuff reduces the amount of ammonia that will be created. If you have gravel as substrate, it won't help as much as the crud gets trapped between the gravel.

I've seen some really massive tanks listed but then it turns out the seller has mixed their mm with cms :slfg:

I find dead spots to be quite useful as that's where the waste all settles, and so makes it easier to siphon out.

Hmm. I was hoping to evict them soon as I need this tank to rehouse a needy family of WCMMs from my goldfish tank. I had 6 WCMMs, of which 1 died from natural causes, and 2 have just vanished -presumably down the mouths of hungry comets. I wonder if WCCMs might leave the fry alone ..??

On a rugby field if you punch a referee you get banned for life. This kid kills someone while racing in a stolen car, then breaks out of incarceration, and gets banned from driving for 2.5 years. Something is very wrong with the justice system.

So what size would they need to be before I can transfer them to the Danios tank?

IT is pretty pervasive these days, and you will need to use a computer to even access this board! My first summer project was to analyse the output of the fetal heart rate monitors used at National Women's back in the 1970s. We recorded the output of these machines and took it to the DSIR for analysis on their PDP-11s ( I think ). One of the scientists there did the analysis for us which was lucky because the amount of Fortran I knew would not have been up to the task! Fortunately the results we got reassured the obstetricians. And the experience put me off live bearers :slfg:

I did transfer a rather sick looking Camboma fragment to this tank from the danios tank so that could be how the eggs were transferred. But I've never seen any fry in the danios tank ... eggs must have been eaten I guess or sucked up into my filter. I must have taken about 20 shots to actually get one that was in focus.

Two and a half weeks later ... don't look like anything in my tanks. Have yellow on their fins. Only 3/4 have survived so far. Do they still look like goldfish?

Trinox lost all or most of his guppies recently in a disaster. Perhaps you could do a swap for some guppies with him for a partially used ammonia test kit? Just a thought since you may be getting too many guppies for your current filtration system to cope.

At the risk of getting this wrong, I would say it's the difference between the top of the water line and where your water outlet exits, and that pump has to overcome this gravitational difference.

ahh.. true. I was thinking of pumps used in fountains and aquaponics where the water level and pump level are the same.

How high it can effectively push the water above the pump.

31 deg C is in the usual range for guppies so you shouldn't have cooked anything. They can go up to 38 deg C. So, perhaps it was the rapid changes that happened after as mentioned above.

Cycled filter needs ammonia to be 0. The levels could be dropping due to water changes since you're not recording nitrites and nitrates.

Larger one is now about 1 cm and I see some stripes so I think they might be Zebra danios.

You might have been knocking back the microbes with your previous method so we might consider that you started back at day 0 when you changed methods.

Did you have to do anything special with your canister filters?

i'd be interested in a picture of your set up
