I would suggest you leave them as they are and not add any more. Big fish need room to cruise without bumping into others.

No idea what it is but I would prefer to sacrifice the one for the sake of the rest. It may or may not be something that will burst and spread disease but better not to take the risk. It is possible he would have paled and gone off his food as the next step of whatever is ailing him anyway and not as a result of being moved.

I have seen them up to about 12cm and they can attack other fish by sucking the protective mucus off their bodies. Having said that, mine never did but I know of a number that did so

You definitely do not put killifish in with giant gouramie or oscars. They are a fish best kept in a species only tank.

It has never occurred to me to buy driftwood. I just go to the mouth of the Hokitika river and pick up pre-waterlogged native hardwoods that have drifted down from the river. Just check for soft, spongey bits - this indicates a rotten bit and it will break up and make a mess in your tank.

Unless you want fry, I would get all male guppies. They are more colourful and no fry to worry about.

That's not many fish (which is good) for a tank that size. You should see some changes soon as it it takes a week to 10 days before levels change as the tank starts to cycle.

What exactly were the test results? Have you changed (or removed) the charcoal since you set up? Charcoal only works for 2 or 3 months then starts creating problems.

Not itself, just in the holes and cracks.

I have never bothered boiling mine (as most were too big). I just scrubbed well with a stiff wire brush and rinsed out all the nooks and crannies.

Very easily! I bet the tuna eat nemo and his friends too

I would wait and see how effective the SAEs are first.

Why do you need another tank? Shift the one you have (into the garage if necessary) while they lay the new carpet then put it back. No problem - except for finding 6 burly mates to help

Welcome - and control yourself until you have the new house to put it in.

Guppies can drop fry every 4 - 6 weeks and can drop several successive batches without needing a fella

Hard to tell from that fish but fluorescent fish are also called Glofish and they are GE. Google will tell you all about them.

When you have a sick fish the first thing to check is the water quality as 99.9% of the time this is what the problem is. Some fish are more sensitive to poor or bad water conditions than others. The most important things to test are the ammonia, nitrite and nitrate levels as this will tell you about the water quality. You can buy test kits from the shop or some shops will test the water for you. What size is your tank, how long has it been set up and what sort of filtration does it have?

I hatched mine in a 1kg plastic Marmite jar using aeration. To get the bbs, I turn the aeration off then use a turkey baster to suck up the bbs which will be swimming in the middle of the water (or shine a light there as they are attracted to light. I then squirt the bbs into a white hanky I have draped over a funnel so the narrow end is in another container and the hanky forms a well at the top. The water then gets poured back into the bbs jar and the bbs themselves are lightly rinsed in fresh water before then dipping the hanky in the tank.

xmamx - you need an excuse? :lol:

They will breed in there whether you want them to or not :lol: If you want to raise a fair number of fry you will need to separate the pregnant females as she and all the other fish will eat the fry as fast as she drops them :roll: Temperature 24 - 26C is standard. Mine is actually a little lower than that at about 22 - 24C and the fish are fine.

Never bothered with it myself and I have a heavily planted tank.

Old credit card works well. Any direct sunlight hit the tank?

Hard to tell what sort of fish they are without a pic but they do sound like dyed or GE fish. I believe you have both in the US. You are right to stay away from dyed fishes!

Not sure what sort of filter is on one of those tanks but what about asking someone to put it on their matured filter to start the cycle ahead of time? Plenty of Wgtonians in here. Or get some used filter media from someone when you get the fish. I would suggest 6 guppies and 4 corys for the base as it is only 21L I think you said. The guppies will swim all over the place and your daughter will like the colours. I assume you have a heaterstat? Some lfs will test the water for you so you don't have to buy kits. In fact, once the tank is up and running there is no need to do tests at all. I suggest you join one of the Wgtn clubs then you will be able to get all sorts of fish and plants from members (often for free)

They can grow up to 30cm and a single adult oscar needs at least 200 - 250 litres of water. That is about a 4ft x 2ft x 2ft.
