There isnt any fish that i know of that will eat BBA, so you will have to try something else id recommend you overdose with Seachem Flourish Excel, i have had good success with this method, you just have to be careful and watch your fish when you do this for signs of stress, if you see signs of stress stop the treatment straight away.
Flourish excel is a carbon supplement commonly used in planted tanks, basically it is an alternative to using co2, one of the side effects of Flourish Excel is that it has algecidal qualities, in other words it kills certain types of algae especially when you overdose it.
The method of overdosing is as follows, usually the treatment lasts 14 days some have to do it longer sometimes up to 3 weeks.
Normally you do a 50% water change on day 1 and add 5ml excel for each 10 US gallons of water, thereafter on each day add 1ml for each 10 US gallons of water. Now those are the normal instructions for dosing excel what you want to do is to start overdosing the excel to kill the algae, so you follow the instructions above for day 1 and then thereafter for the other days you dose the excel at 2 or 3 times the recommended amount so you will be dosing at 2-3ml per 10 US gallons of water.
Personally i have found overdosing 3x to be most effective but watch your fish, just be aware that it can also kill certain types of plants as well when you overdose it like this.
You will know it is working as usually the bba turns red or reddish before it starts to die off
In you case i would start to dose the excel at normal doses and i would increase the dose gradually until you start seeing results or are dosing at 3x the recommended amount.
One thing that is glaringly obvious about your tank stats is that you have zero readings for nitrate, plants use nitrate as a very important foodsource, in low light tanks it is the fish that will usually provide this, having 0 nitrates in planted tanks will normally induce algae, you also have very low readings for phosphates and this is another important foodsource for plants as well also usually produced as a by product of fish and food waste, and just one last thing that i notice you also show readings for ammonia or ammonium, is this tank cycled or just newly setup or something like that, not that it makes much difference to the algae now that you have it, im just curious.
Good luck with the treatment, just go slowly at first and then increase the doses, you can do water changes as normal during the treatment but add back in Excel at 5ml per 10 US gallons and then overdose as described above for the other days.
