i eventually got my 2 blind cave tetras and theyre pretty cool. they might not be very "pretty" but i reckon they make up for that in so many other ways.
just as a wee kinda aside to everyone - when thinking about getting a clean up crew (shrimps cories etc) think about these blind cave tetras. i know theyre tatras and arent typically a clean up crew - but since having them my tank has never been cleaner. i think its because they have no eyes they can small better or someting because they find every last scrap of food in the gravel and eat it, much better than any of my cories do.
they also seem to be quite resistant to disease as i have a bad case of white spot in my tank just now and these are the only 2 100% completely unaffacted, while others are covered in the spots from head to tip of tail.
theyre also very entertaining because they are extremely active, but are peaceful and have never once tried to nip anyone fins, or annoy anyone at all which i think is unusual for tetras. they also grow a lot bigger than most tetras (4" i believe) so arent going to get eaten like neons or cardinals might.
so basically, i just wanted to let you know that theyre a great wee fish, and i recommend them to everyone if youre thinking about getting more fish for your community tank
