Since you will not tell us your exact readings, anything I say is based on the assumption that your readings are as follows:
* ammonia: 0 ppm
* nitrite: 0 ppm
* nitrate: under 25 ppm
* pH: 6.7-6.8
* water hardness: soft
* temperature: 27-28 C

What size are the loaches and for how long have you had them?

Please post a precise stock list, including species and numbers. Describe the décor, especially how many caves you have (a photo may be helpful).

When you say looks dead, can you describe that in more detail?
