Possible returned 1.5 gallon tank, ideas please?

HI all, I bought a 1.5 gallon (7 litre) nano tank and, not realising exactly how small it would be, wound up ordering a 29 litre tank soon after. Upon seeing my very happy 29 litre set up with 6 Endlers Livebearers and blue diamond shrimp, my father-in-law wanted an aquarium of his own, so I said he could have the 7 litre and could probably put something like a couple of tetras in it with some shrimp, but that would be about all. I thought he'd listen, but I was wrong.

Last week, I got a phonecall to say that his guppy had eaten his shrimp. He now has three guppies in a 7 litre tank and when he went to the pet store this afternoon, they refused to sell him anything else for the simple reason that his tank was overstocked. Understandable, of course, even if he cursed the poor woman out. He's now talking about buying a larger tank.

I've told him that if he doesn't want the 7 litre tank then I would like it back (it did cost me about £50 with the heater). I thought about a betta fish but it's too small by at least a gallon, and they need soft water whereas mine is hard. Shrimp are fine, but we have some in the larger tank so I'd really like to look for something else, if at all possible?

Many thanks!

 

I think shrimp would be the only thing I'd be comfortable putting in that. I'd maybe go all-out doing a super minI aquascape, and getting a color or type of shrimp that isn't as usual as cherries.

 

Only do shrimp or a snail. shrimp would be better though.

 

Shrimp or maybe ThaI micro crabs

 

Hmm thanks all. I'm thinking I might go with a super small set up on my desk. I've got at least a dozen blue shrimp in my 7.5 gallon so I might transfer some over with sand and some small plants. I wanted to go for fish but shrimp are just as fun to watch. We have one who seems to spend his days hopping between the moss balls!

 

If it’s good condition, you could sell it second hand? If you want a second you may be able to get another second hand for same price?
All my six tanks are second hand! Only one leaked :/!

 

Thanks all for your suggestions, it's all set up with 4 blue diamond shrimp in it. I was hesitant about shrimp at first but they have quite the character! I had to pop one of them back into the main tank as he seemed far too active, riding up into the flow of the filter and whizzing around and around in the tank. The four now are more happy cleaning and having a gentle paddle about. One definitely noticed me put a tiny bit of food in earlier, he swam up to steal a piece! Who knew shrimp would act like fish in the end?!
