I recently purchased 2 glass cats and they are great. just wanted to share a cool combination to try in the near future. ( if your up to it or starting a new tank) Glass cats are super, and they make a good combo with chocolate gouramis and colourful guppies My favourite fish so far are definetly glass cats, and chocolate gouramies, very beautiful fish especially the chocolate gouramies, what with there beautiful strips, gouramies look fancy and expensive, as do glass cats. having said that, chocolate gouramis are VERY hard customers, when i bought 4 only 2 survived so gouramies are for more experienced fish collectors. glass cats are hardy though and easy to keep. Any other combo suggestions?
