Black moor lying on bottom of tank

Recommended Posts

Hi, hoping you guys can give me some advice about my new fish.

 

A family member had two black moors that had to be rehomed at short notice, we took them ten days ago. There was no time to do a fishless cycle, so we got an API testing kit, some gravel from their old tank and a bottle of Tetra Safe Start and hoped for the best.

 

We have them in a 135L tank, they were in 40L previously. We have a decent filter.

 

The smaller of the two fish (although they're both pretty small) seems to spend a lot of time lying on the bottom of the tank, although he perks right up when someone comes in the room. The bigger of the two seems fine, although we're a bit concerned he's bullying the smaller one!

 

We've tested the water every day and the parameters have been the same every day:

pH 7.8/8.0

Ammonia 0.25 ppm

Nitrites 0 ppm

Nitrates 5 ppm

 

which I think is ok, 0.25 ppm ammonia wouldn't be harming the fish would it? After testing each day I feed them and then change about 15% of the water.

 

Family member was feeding them a pellet each twice a day, I've been putting two pellets in the tank once a day as I know I shouldn't overfeed while the tank is cycling. Is this enough? I'm a bit worried the small fish is resting as he's starving! Plus he seems less good at finding the food than the bigger one and I can't work out a way to guarantee he's getting fed.

 

Any thoughts would be much appreciated!

Welcome to Kokos and I hope he feels better.

Relax, you will be fine.  Could you please estimate the standard length of these fish?  That means the length from the nose to the base of the tail, but not including the tail.  How big are the pellets?  Don't worry, I've never heard of anyone accidentally starving a goldfish.

 

Please test your tap water and report what you get. 

 

Actually 0.25 ppm ammonia can harm fish, but you can protect them.  Get a water conditioner that removes/inactivates ammonia.  Seachem Prime is one and Amquel Plus is another.  I don't know what is available where you live, but a pet/fish store should have one of these or something similar.  These protect your fish from small amounts of ammonia.

 

I recommend you change 50% of the water to see if that makes the ammonia too low to read.  Then up your current changes to 25% and see if that improves things.

Thanks for replying. I'd say the larger fish is about 2 inches and the smaller 1.5. Food is Tetra pellets for fancy goldfish, they'd be about an eight of an inch I guess?

 

I've done a bigger water change of about 35% today and treated the whole tank with Prime. I've been double treating the new water each day, which I read to do somewhere while cycling. Water parameters before the change were as above (although the ammonia isn't as dark as the 0.25ppm colour on the test card, it's always a bit lighter, but definitely not zero). After the water change the ammonia is similar, maybe a bit lower, I haven't retested the other parameters.

 

pH of tap water is slightly lower than the tank water and the ammonia is also lower than the tank but not zero.

 

If the tap water has non zero ammonia and the tank has higher than zero nitrates all along, how will I know when the filter has cycled? Do I need to wait for nitrites? Given the safe start solution and gravel from their old tank, it should be quicker shouldn't it?

 

Little fish has still been spending time in his corner at the bottom of the tank. But he comes out as soon as I go over, presumably as he thinks he's going to get fed, and at other times as well. But as the other fish never does this (haven't seen it once) and I haven't had fish before I'm not sure if it's ok or not.

When the tank reads zero ammonia and zero nitrite before a water change it has cycled. The gravel will probably help some, the Safe Start probably won't.

Great time Jeana. I was just coming on to post on the Disease and Diagnosis forum. The poor little guy isn't well at all and I think I might have to euthanise, was looking for advice.

 

Water as it was before, have been doing daily changes. Other fish still happy out. 

 

Other fish was being very aggressive last week and came home one day to find some damage on the little guy's fins (the one who'd been sitting under the filer). I wasn't sure if it was because of hunger or illness and so upped the feeding for the big fish and that seems to have helped. I had been fasting in case little fish was constipated so the bigger one maybe wasn't too happy with that!

 

I've tried peas in case of constipation.

 

Anyway, the little guy is now bent over and his fins have a lot of damage. He's also now not too interested in food. I got melafix at the weekend so I was going to give him until the weekend when the 7 day course would be over but he just looks so miserable tonight I'm wondering if that's cruel.
