The tank these guys are in is the first one i have had for only livebearers (more into ponds with natives and want, no need a monster tank in the house), so of course since everything I checked said to use aquarium salt for the platies and swords. Is the aquarium salt ok for the ottos??
I know I'll still need to use the scraper, but I'd like to use it a little less often.
thanks for all the info so far.
