Why are my blue gouramis hiding?

Question

My blue gouramis (male and female) are hiding down at the bottom of the tank and have been doing so for a while. What could be causing this? Other fish in the tank (55 gallons) include glow-light tetras, black neon tetras, and a pleco. Any information is appreciated!

Answer 1

when i got mine they were fighting. maybe thats it

Answer 2

blue gouramis are the most difficult and sadest fish to look after

when i first got myne it was unlively and hid behingd things

so i put in another one for company

the old one chased the new one taking bites and nibbles out of it

then i took the new one out and gave it back to the fish shop

after a week my new one got sick and dyed

there the worst gouramis to look after
