Hi Karrie, welcome to the site, are you able to post a photo of him?
Following is some information to help you out:
Tank size: 60cm long x 30cm long (for 1 axie) minimum. If you intend getting another axie (they kinda grow on you and one is never enuf once you get the hang of it!), 85cm/90cm long x 30cm long. Bearing in mind they can grow to 30cm by the time they reach adulthood, axies are better in longer (floor space) tanks rather than higher.
Temp: they prefer cooler temps than that, as heat can stress them and fungus can develop. Axies will survive in as low as 42 deg F(5 deg cel), but between 60-65 deg F is a good temp to keep them at. Above 71 deg F you will have to cool the tank (fan blowing across surface is one method which can help).
The fish probably nibbled at his gills, which is why the best companions for axies are either other axies, of same size, or no companions. Keep an eye on him tho, just in case he looks sick or starts developing fungus.
Filter: use one that doesn't have a strong current flow, or one that can be turned down or divert the current somehow so it isn't as strong (ie if you have a spraybar on it direct it towards the back of the tank so the water hits the glass b4 going into the water)
Substrate: none, sand (pool filter or playsand- thnk you can get them from Walmart) or large pieces of slate/rock as they are easier to clean and the gravel won't block them, in turn causing more probs. Since he has been on gravel, and now is not, you may find he will poo out gravel until it clears his system (this can take up to 7-8months depending on how much he swallowed to get rid of it all).
Food: Best staple earthworms (think you call them wrigglers?).

Did you cycle your tank?
