Something fishy...

Couldn't be more wrong!

Coldwater fish are harder to keep as you don't have the stability of a warm water tank due to fluctuations in temperature in the day & night and as has been mentioned, coldwater fish emit more than 6 times more waste (ammonia) than tropical fish which is why when calculating the amount of fish you can keep you can't keep anywhere near as many coldwater fish due to those examples. Also whether the tank is cycled or not, you do never put all the fish in at once, you slowly add a few fish at a time (floating the bag) so the beneficial bacteria, which you cannot measure the strength of when at zero, can cope with the ammonia spike and consume it as food and convert it accordingly.

Also, virtually all coldwater fish are hybrids, man made and imported from the Czech, as such again there is more stability and knowledge with tropical (true bred) fish, there is also not a fish on the planet that will keep a tank clean! You can obtain a vegetarian fish (various sucker mouths) that will attach themselves to glass and rocks but it is impossible for them to clean a tank per se and should still have their own diet fed to them, only gravel cleaning with the correct syphon whilst doing a 20% water change, washing the filter in that water to protect the bacteria and then before adding new water back dechlorinated it and replace it slowly but also add some more liquid bacteria due to the water taken out will keep a tank clean & healthy.

A 14l tank will hold next to nothing as it probably won't hold that in actual water volume after dispersion so you have less than 3 gallons, in colwater terms that's 1 fancy goldfish, its not big enough for a standard goldfish so I would opt for a small shoal White Cloud Minnows which are temperate fish, do not overfeed!

This is the kind of good advice I was talking about. Certainly helped me move from a very small 28L to a nicer, sirprisingly easier to manage 240L.

We keep water not fish, I always stated this when writing for magazines and consulting all my customers, learn how to look after water and the fish will look after themselves ;)

Absolutely. Just had a drop in PH for unknown reason and lost two Silver Sharks. Bit of crushed coral and all back to normal. It was the poor water that did the damage.

Very good advice that. :thup:

Looks like I'm no good at keeping either...

Schoolboy error as the level of the water in the tank wasn't high enough for the pump to filter it correctly :( Back to square one.

Fish, the forummer, I will PM you later with a couple of questions if that's ok??
