Hello I'm a new member here... first post! I have had my 210l (planted tank) for 2 years now and I'd really like to add a few more fish - it looks a bit empty Stocked with : 5x platys - sunset/mixed 1x Guppy male 1x Honey dwarf gourami 5x peppered corys 2x gold barbs (believe me I've tried introducing more - these two almost killed them all ) And lots of plants - don't look to good at the moment except the java moss/indian fern. Will be getting a new load soon. After browsing I cam across some boesemani rainbows - which I'd never heard of! They're so gorgeous!! But I think my tank isn't really fit for them as much as I'd love to get a couple. I heard they need tanks of 4ft +, whereas mine is only 91cm long. Tank dimensions are 91long x 48wide x 50cm (water line when tank's filled really high) pH has always been under 7, normally 6.5. Ammonia/Nitrites/Nitrates all 0. I do have pHUp which I thought I could start using if I were to get boesemani's - they need pH 7-8 right? Does anyone think I could keep a few boesemanis with them living happily? Question is; is my tank suitable for 3 rainbows say 7cm long? Even if pH is under 7 (or I could get it up if necessary)? Any suggestions would be appreciated! Oooh I also heard about the neon dwarfs, which I'm pretty sure suit my tank - only thing is from photos I've seen they look less colourful... not unpretty - all the rainbows I googled are beautiful- but less colourful than the boesemani's. If I'm not allowed boesemani's, would they be a good 2nd option? Thanks!
