Could I add another fish?

[fishman256]

Hello,

I have a 48"x12"x15" with an old IPF3 from the previous set up and a fluval 3. The inhabitants are 5x2" congo tetras, 1x6" synodontis catfsih, 2x2" spotted dollars, 3x4" SD's and 2x6" yelow hooks. I think that I have enough room for another 4" fish but I am firstly not sure what I could put in and secondly whether I am already fully stocked.

I am also thinking of upgrading the old IPF with something more modern.

Feedback will be appreciated.

a ctenopoma might be an interesting option, they are pretty neat fish

glass cats are cool

What species is this synodontis? Glass catfish may be unable to compete the silver dollars for food so they are out of the question unfortunately. How about golden panchax? These are predatory killifish growing to 4 inches max. Tight cover is required as these are excellent jumpers.
