Ok so I have been keeping datnoids awhile now recently bought couple here and their to have a group in my tank. So today I order 20 more around 1-2" and raise them up. Look out datnoids keeper I'll have picture when its here
Even a 300gal is way to small for 20 tigers you will need 2000 gal +lol I have a 300g tank for them but first its going in a 150g so they can find food easily
