Hello,

I am a new tropical fish owner from the UK, having kept goldfishes as a child in the past.

I am having my fair share of problems and am doing a fish-in cycle.

Here is the info on my setup:

Fishbox 60 cm Tank by Interpet 64 litres - apprx 15 US gallons
Interpet Deltatherm Heater 150w
Interpet Internal Power Filter - PF2
3 plants - can't remember the names but they are two long ones and a short one
Black gravel
Small sea shell decor - has air bubble feature
Building monument decor - has air bubble feature
Interpet Filter Aid 100ml
Interpet Tapsafe
Interpet Airvolution Aquarium Mini Air Pump with tubes
General cleaning stuff like bucket, jug, net, gravel cleaner


Events:
On Fri 20/05 I setup my tank without fish or plants or decor and left it running with lights, heater, filter, washed gravel. I put tapsafe and filter aid also in the water. My water was clearish for a time and then cloudy.

On Sat 21/05 I went to my local aquarium centre and bought five hardy Harlequin Rasboras fish all from the same tank, plus plants, decor and cleaning equipment.

The journey home lasted no more than 30 mins, and first potted the decor and put the plants in the gravel. I then let the bag with the fish float in the water for say 10 mins, then opened the bag added water from the tank into the bag and let them sit for 5 mins in the bag. I then used a net to take the fish out and discarded of the bag and water that they came in.

Before I put everything in my water was cloudy and after my water was also cloudy. The fish seemed to lay low but then came out huddled together and swimming around exploring the tank - this was late afternoon.

I realised at one point that the filter bubbles seemed to powerful a current for them, so adjusted this to slow them down as they kept getting blown away by it. Towards the night they seemed ok and were swimming less fast but active.

As directed by the shop I didn't feed them today as they were fed that morning and he said feeding once a day tomorrow is fine.

On Sun 22/05 I wake up at around 6 am worried about the fish and find one dead after counting so many times. I inspect and can see that the back fin got trapped by my filter nozzle and it was lying on its side. The fish looked in good health though when I looked at it.
I change the direction of the nozzle to center it as it was more one sided before, which has narrowed the gap. I aid Filter Start to the water (x2 1ml droplets every other day is the dose I am using).

I feed a few crushed Aquarium tropical fish flakes but they see the food and ignore it and carry on swimming at the top. After 5 mins I removed it and try to discard most of it using a net.

Problems.
1. The fish have not eaten since 21/05 in the morning. Why are they refusing to eat?
2. I notice they spend most of they're time at the very top of the tank making air bubbles in the corner by the heater. Is this normal? My heater is set at 25 degrees. I am starting to think that they don't have enough air?

Even though my air pump is switched on, I think I have set the tube connectors up wrong as they are not pumping bubbles. My filter however has a Venturi for bubble effects which has been on from day 1.

I am worried that the plants and fish will suffer if I can't get the air pump working, is it needed if I have the Venturi on?

3. One fish has died because of the filter nozzle. It was definitely trapped by it and suffocated. I don't want this to happen to the other fish, so have centered it. I am thinking maybe that fish was not strong enough to swim away from the current or is it the filter's fault? Should I turn up the Venturi so it pushes away the fish and they can't get trapped again or is centering the nozzle enough?

4. I am confused when I use the net to fish discarded food or the fish out, do I have to use Tapsafe? I ask this as I rinse off the net it tap untreated water and let it dry in my bathroom. Is this ok? I thought it would smell if I didn't rinse it off.

5. I notice a kind of faint greeny line in my clouded tank water. Is this due to the plants?

6. What care can I give the fish so they don't all die or what do you think I should do? I really don't want a fishless cycle, I am very new and thought it would be easier to do a fish in cycle as you don't need to add ammonia?

The guy in the aquarium centre did say I may lose 1 or 2 and said its best to do a fishless cycle but I said I wanted to do a fish in cycle. He said that in a week I would need to do daily 20% water changes.

I posted here first and will call the shop I bought them from also. I also am going to try to get an API testing kit today and take a sample to the shop to test.

Ultimately I would love to have a Betta fish with a select few community fish.

:huh:
 
Welcome to the forum goldentipz. The first 3 things you need to do are: 1. do a large water change, at least 50% 2. get a test kit to test your water and 3. read this article http://www.fishforums.net/index.php?/topic/224306-fish-in-cycling/


Your fish are gasping at the surface because they are not getting enough oxygen. This could be do to lack of oxygen in the water column which will be solved by a big water change. It also could be because their gills have been damaged by ammonia. A large water change will lower the ammonia level in your tank.
 
+1 to what Randi suggested. Letting the tank "sit" for a few days does nothing. You are now in a fish-in cycle situation, which means LOTS of daily testing of water and water changes to keep ammo and nitrites below 0.25 until you are cycled. Get a test kit ASAP and continue to monitor the levels and change water as often as needed to keep the water safe for your fish. At least the guy did mention fishless cycling, which is good and a better method; less stressful for you and the fish. if you can take them back and go fishless, I would recommend it. What he said about daily 20% water changes is incorrect. YOu may have to do larger pwc each day, sometimes multiple times a day depending on your water levels (which is why you need a test kit, NOT the strips, liquid test kits are more accurate. The API Master test kit is the best). For example, if your test kit shows 1 ppm ammonia, a 50% water change would get it down to .5 which is still too high, you would then need to do another 50%+ water change to get it down to 0.25 or under. A good dechlorinator is a must as well (I use Prime which is said to be the best) and match the water temperature of the water you are putting in as close as you can to the tank water. Keep asking here for advice, everyone is very knowledgeable and helpful. Good luck!
