Hi.
I have a 150 litre tropical set up. Fully matured and properly maintained.
6 male guppies, 5 honey gouramis,8 neon tetras and 4 very small corydoras.
Was bought an L200 for my birthday together with another small 4-4cm striped pleco.
The L200 died within 10 days, the striped pleco is feeding, active, everything you could want.
Not new to keeping plecos, plenty of hiding places,put down cucumber, potato, algae wafers etc.
Should I get another one and try again?

I wouldn't recommend getting another until you know hwy the first one died. Was it perfectly healthy when it came from the fish shop?

Yes it was a healthy strong specimen, not stressed on the short yourney home,acclimatised very carefully. I had reserved it in the shop for 10 days before I picked it up. None of my other stock have any problems. Was I just unlucky?
