i have 2 small Ctenopoma acutirostre for sale after changing my stocking plans for a new tank. they are still quite small at about 2 inches max, my plans were to grow then up and put them in with my bigger cichlids but ive decided to stick with just cichlids now. they are both very healthy and eating like mad so im sure it wont be long before they are hitting 4 inches. they grow to a max of about 6 inches and are a predatory fish but not aggressive so small neons etc may not be great tank mates. i use to keep some with discus and angels with no problems and smaller fish like platys and larger tetras etc. i paid £15 for 3 but 1 is no longer with me so ill let them go for £8 for the 2 ono. i will not post.
