All But Bottom Feeders Die

[andyjam]

We are quite new to fish keeping. We bought our tank about 8 months ago. We set up slowly and had no troubles for a while. We have foxgloves, catfish, mollies, guppies and Clown Loaches.

They all seem fine - very active until the next morning when one by one they die! No strange swimming - eating well etc. We have had several lots of guppies, mollies, tetras, and now angel fish who have died - The bottom feeders are the only ones who have survived this whole time - and a baby Molly which was born in the tank! Seems everything that lives from the middle up doesnt live anymore!!

Any advice?

Welcome to AA!!!.

How large is the tank? What are the test levels? Do you have a test kit? How often do you change water and what are your maintenance procedures?

100 L tank, Ph okay, no other kits, change 1/3 water every 1 -2 weeks. Clean filter every month. water clear. no spots etc on fish. Lots of plants.

You really need to get an ammonia and nitrite kit. Get a liquid test kit they are much more accurate than the strip tests. When you clean the filter do you throw out the sponges and stuff or do you rinse and reuse them?

We rinse the sponges and reuse them.

I will get a test kit tomorrow and let you know! Thanks!!!!!!
