I have a new 90L tank that has been running for about two weeks. Its one of those Hexagonal tanks on a stand and has an under gravel filter.

It currently has 3 adult swords, 3 young guppies, , 2 young pearl gouramis and a small plec. At the moment I am having to do 40% water changes every day to keep ammonia levels under 0.25ppm. I dont mind doing this but next week I have to go away for 6 days. I have an auto feeder but worry about my ammonia levels. Should i put all these fish back into my 350L understocked cycled tank or just some.

Any suggestions please.

Why did you take them out of the other tank?

Don't feed them for the 6 days you are away. That will help keep levels down.

Unexpected work commitments.

I was thinking of adding a weekend feeder instead of regular feeds.

Will they be ok for 6 days with no food?

Yup they will live fine for a week with no food.

If you are worried about the ammonia move some of the larger fish back ( the mollies maybe ) I would leave the pleco jsut because they are so hard to catch :lol:

If you are having to do big water changes to control ammonia you probably have too many fish while the tank is cycling. If you just had the guppys and a small pleco in there the ammonia level would be much lower. Then after a couple of weeks, add a couple more fish.

Thanks. I will do that. I think that i have probably been overfeeding them as well which has contributed to the ammonia build up.

I leave my fish a week to 10 days with no food at times and it doesn't harm them. You may find a bit less algae in the tank on your return and some fish very happy to see you

My New 300L Tubular acrylic Tank arrived today ( yee ha). Its 700 diameter and 750 high (plus Stand). Ive just got it filled and will leave it for a few days to heat and settle. I was thinking that i could take my 3 adult swords out of the hex tank and put them in the new tube tank along with 2 small gae's and that they would be ok for the 6 days while im away and would help the new tank to start cycling.

Whay do you think?

Here is a couple of pic's of the new tubular tank.

I hope I get this right.

As you can hopefully see, I still have a lot of landscaping and planting to do before it looks anywhere near as good as is can.

sorry about the pic's, I was in a hurry

trying again.
