Catching Mr. Smith

What do you do with a leaking fish tank whose lone occupant is an eight inch long algae eater?

We bought the tank for our elder daughter in the 1990s. It was her Christmas present, something she really wanted that year. She spent quite some time choosing the fish to go in it, reading about proper tank maintenance, etc.

Over the years, the fish population changed. In 2020, there were only two; a beta and an algae eater named Mr. Smith. Mr. Smith was around five inches long at this point. That was something of a surprise, as we weren't told they'd grow that large when we bought him.

When our younger daughter left home, tank care became my responsibility. This wasn't easy to juggle along with everything else, but we muddled along until August of this year. I was down at my mother-in-laws house and got a call that the tank had sprung a leak.

My husband stopped the leak, but we knew it was a temporary fix. We needed to do something with Mr. Smith, because the leak would definitely come back. But, by now he was over eight inches long. He was bigger than the biggest net at the fish store. Plus, we knew by now that he was an incredibly fast swimmer.

We found a home for him at a local fish store. The store has a good reputation, so we have hope that he'll find a good home. The only problem was how do you get an eight inch algae eater from the tank in our house to the new tank at the store?

It wasn't easy. In fact, it took forty-five minutes. First, we bailed out water into his "travel bag," as instructed. Then we bailed out more water so he'd have less space to swim.

He was not amused, and started flitting around the bottom of the tank, stirring it up. Finally it came time to employ the net. I have *never* seen a fish do a barrel roll. By the time we got him into the net and sort of into the bag, we thought we'd killed him.

I put the net, fish and all into the bag, then carefully disengaged his fins from the net, where they'd become stuck. I was feeling sad, because I really did think he was dead.

Once free of the net, however, he started moving. Not much, but enough. I called my husband and we rushed him to the fish store. I told the owner that we thought he was still alive, but he needed stress coat (a liquid that helps soothe fish in shock and for other fish needs) right away. Obligingly, she checked him, dumped some in and told us he was fine.

When we left, Mr. Smith had moved himself into a corner of the new tank, and I promise I think he was sulking. Not even a catfish that swam over him moved him. However, he was very alive…and just fine.
