Thank you for your comment
I have had Houdini for a little over a year, and have had no visible problems with his health. After his first escape I refortified the aquarium with a terrarium mesh lid, and cut out a hole for the backpack filter. The second time he escaped I believe i left the lid ajar, the third time I have no idea. This time I think I may have left the water level too high, and he was able to, against all odds, launch himself against the stream, into the backpack filter and then somehow out. I'm making a mesh dome out of a colander to prevent this from occurring again. I respect this creature a lot and am not a negligent person. Perhaps he isn't comfortable in a ten gallon aquarium, or maybe he's simply adventurous.
I do a 50% waterchange once every two weeks
Houdini is the only creature in the aquarium, save for guppies that he munches on
I use city water, and treat it with "Prime", I use three drops to the gallon
I keep his water temperature constant between 13 and 17 degrees c
About a month ago I switched the gravel out from small pebbles to large gravel, because some of the pebbles were small enough to swallow, but the gravel is only about 1.5 inches deep, is that ok?
Any comments on his long term health are appreciated, however
Please refine comments toward Houdini's IMMEDIATE health needs!!!!!!!!!!!!!!!
Thank you
