Merry Christmas all xx

Hello Colosseo and welcome to fk sadly a lot of fish shop staff are not in the know when it comes to fishless cycling a tank, or they are told what to advise, and a lot are old school where you use fish to cycle it and end up like yourself with dead fish Cardinal tetras are quite sensitive at the best of times so not good for a un-cycled tank
To answer your question, you can start to add the Ammonia straight away we do have information on this method so will find it for you another method is using filter media from a mature tanks filter not the water, so do you know anyone local that has a mature fish tank set up at all

here you go

Hi Kingkong Sorry you haven't had a reply before now, how have you got on did you figure it out at all not familiar with your filter but on my Rena XP externals the outlet is on the left and inlet on the right, the filters usually have a diagram on it to show which is which

Wish there had been a different outcome as its not an easy decision to have to make but you did the best you could for Sandy, condolences

The kindest way recommended is to use clove oil (used for toothache in humans) you can buy this from the chemist/drug store, and once the fish is asleep add a little vodka as this prevents the fish from waking up I have sadly had to use this method myself on a large goldfish with an internal tumour and he just went peacefully to sleep

Some reading on the clove oil method

if you need anything explaining then you know we are here

Oh my poor love I would say it is a tumour

The choice you have is, do you want your fish to live upside down like this, many fancy goldfish do due to swim bladder problems but they don't tend to have a great big tumour attached sadly unless you know a fish doctor it may be kinder to put your goldfish to sleep if you decide on the latter we can help you do this gently, where he/she will just go to sleep and not wake up

Hello Peter sorry no one has replied to your question sooner, I am not the best person to advise on Discus as I have never kept them but going by the care-sheet prawns are safe to feed to them I would presume cooked and cant see why you cant freeze them as long as they are fully defrosted before feeding to the fish hopefully someone will confirm this or not for you

Mine tend to send runners that reproduce new planets which can be pulled up and replanted into another tank if needed

as seen in this photo https://www.flickr.com/photos/goldy/10 ... /album-72157625061664724/

Other wise you can cut a piece off with roots attached and replant but will mean pulling a bit up to get to the root

Looking at the photo and shape it appears to be a fancy goldfish, either a fantail or possibly a Ryukin "it does have a double tail doesn't it" only a baby at the moment so as it grows you will know for sure if its hump gets more prominent

Have you tried uploading it to the photo gallery at all just bare with me not done this myself in a while so will see what the problem is for you if I can ok
