Thank you for the great comments everyone . The lights are at present a 5ft twin flourescent hanging from ceiling above and a twin spot light at back also hanging from ceiling but they are the kind that make everything yellow so need to get lamps changed to show more colour . The tank cost £850 and was made on site , I just fitted concrete blocks under a sheet of 18mm ply and they supplied another sheet of wood and glass. Full stock Jag. Red Terror Red devil. Green terror. Oscar. Female dovii. Bouccori ( spelt badly). Jd. And a few cleaners . I intend to play with stock as they grow and hope to get maybe 6 full grown males as final setup others will go in my older tanks
