One Fish Left... Does He Need A Friend?

[AllisonJoy]

I started a freshwater 5 gallon tank with 6 "glofish" in May. 3 died shortly thereafter, I believe due to the fact that I did not cycle the tank and I had too many fish. The nitrate and nitrite levels were both very VERY high. Two more died about a month ago. Nitrate levels were a bit high, but not very, and nitrite levels were fine. I use chemicals to treat the water every time I add more water and weekly.
 
I now have one fish left, and for awhile, I thought he wasn't going to make it either. I've started turning on the LED lights, and he seems to like that, and seems to be doing better. I'm trying to figure out if I should get a couple more fish. This may sound weird, but I wonder if he's lonely?
 
I don't want to get more fish only to have them die again, but my take looks quite empty with only one fish in there. Any advice?

I'd rehome him if you can, glofish are too active for a 5 gal, sorry.
 
Once you have rehomed him, have a look at THIS thread for suitable fish.

Have a look at it this way would you like to be alone? I agree with blondie though you should try to rehome him. If you decide to rehome him before getting any more fish make sure that your water levels are alright first. Many shops will check for you to make sure its alright. What water do you use for water changes? Do you get it straight from the tap and then use the chemicals?

5 gallons!!!! You need at least 50 gallons for Goldfish as they DO grow large.

This thread is about glofish, the genetically modified zebra danio, not goldfish, Carasssius auratus auratus!

My apologies I must wear my glasses

Easily done
 
In reply to the OP, yes, he will be lonely; zebra danios are a shoaling fish that live in groups of hundreds of individuals in the wild. I also agree with blondie; although small in size, zebra danios are very active fish, and ideally should have at least a three foot long tank, so it probably would be best if you could find someone else, who has more glofish and a bigger tank, to take him.
