Hi All
recently renewed my interest in tropical fish from a young age so effectively starting again from scratch.
i have just bought a 95l tank which i set up and left for 10 days prior to getting any fish.
i bought 6 tetras to start which have now been in the tank approx. 3 days.
i did as advised by not feedeing for the 1st 24hr then only fed small amounts.
however none of the fish seem to have a very good appetite and are now looking rather lathargic.
is this common or is there a problem in my tank.
i have 3 oxygen eminating plants but no air stone fitted, could this be an issue?
Any advice given greatly received.
regards
Richy
Hi Richy,
to the forum.
Your problem is that your tank isn't 'cycled'. That means it doesn't have a colony of good bacteria living in the filter that eat the fish's wastes for you, so those are building up in the water and making the fish feel ill. Just running a tank won't cycle it; there needs to be a source of ammonia present for the bacteria to feed on before they'll start growing.
You need to do an immediate (sorry I didn't notice your post earlier; this isn't the best place for advice; might be a good idea for you to post in the 'Your New Freshwater Tank' forum in future!) large water change. Drain nearly all the water out, leaving just enough for the fish to swim upright, and refill with warm, dechlorinated water. Don't forget to switch of your heater and filter when you do this!
You'll probably be having to do that every day for the next month/six weeks or so, unless you can beg/buy/borrow some already mature media (that's all the stuff in the filter) from an established tank.
We have some great articles on 'The Nitrogen Cycle' and 'Fish-in Cycling' in our beginner's resource centre (the link for that is in my sig) which it might be a good idea for you to have a look at.
