So my 75 gallon sprung a leak Saturday night. I drained it, and put the rasbora and Apisto pair in a 15 and 10 gallon, as well as the plants. The wood and large rocks sat out on a towel, and I just replaced the gravel with sand a few days prior. I did leave some water in the filter, but wasn’t running. I got a new 75 gallon set up the following evening. Any chance any bacteria from the filter, rocks/wood survived? I put the rasbora back in the 75 because they were slowly getting picked off by a killifish. Kept the Apisto pair in the 10 gallon for now. I’ll be testing the water periodically, but wondering if this will be like a new cycle...
