Red Tailed Black Shark 4-5cm
The Red Tailed Black Shark is an old favourite in tropical fishkeeping. Their all-over jet-black body with a bright red tail looks awesome. These fish are loners and are intolerant of their own and related species. They are mostly peaceful, but territorial, they can be aggressive to other fish that occupy the same areas. This includes loach species and most cichlids. Keep in an aquarium at least 80cm (70L) long, preferably larger as these fish will grow to around 12cm long. Red Tailed Black Sharks can be kept with medium and large community fish, but it would be best if they are the last fish to be introduced.
