Good home? I've been trying to kill him for the past week

put him in a 10 gallon quarentine that I thought was cycled but, uh duh, he's alot bigger than a
betta and a cory cat.
ammonia spiked in less than 3 days (got up to3!!! I think feeding live blackworms the first day was a really bad idea they got into the gravel and were uneaten),
nitrite is just now starting to go down from 1.6, and the
pH keeps jump between 6.5 and 5. Been doing water changes like crazy (25% twice a day, and 50% when the spikes happened), still sucking up fragments of blackworms (I swear I didnt put this much in here, it was the aliens!!) But he's hanging in there along with his cory cat buddy. Fingers crossed and praying in front of the tank seems to be the only other thing I can do.
