I just bought a 5 gallon tank and I do want a male Betta. What would be some good tank mates? I was thinking about buying a Mystery Snail as well but I would like more. Also, I was really looking forward to buying an Upside Down Catfish. Any suggestions for me?
IMO (and I'm not alone on this) a 5 gallon is really too small for tank mates.
The only suitable tank mates for a 5 gallon are 1 mystery snail or a handful of shrimp.
The good news is that if you're into shrimp you could buy a few ghost shrimp to start with then get some cherry after a month if the ghosts aren't eaten and if the cherries aren't eaten after a while then you could go for more exotic colors like Crystal Reds, Bee, Green, Blue etc. =]
Just make sure to check out this page (and the site as a whole) first before you make your exotic choices as interbreeding will destroy the color of your new shrimp. =]
For example red and yellow shrimp don't make orange shrimp. The fry just revert to their natural brown coloring. =[
Also remember that if you keep shrimp in a predatory tank they need PLENTY of hiding space (lots of plants and such) and that you might not see them often as they might be scared to come out of hiding. =/
I advise getting a 10-30 gallon if you want tank mates because then you could have shoaling fish! <3 Like corycats! I'm not sure about the upside-down catfish but I believe that I just saw an article about them on our Parent forum Tropical Fish Keeping... I'll go look for it to see if they're compatible with betta fish. =]
