Point well taken. It does take a few months for them to grow to 3/4" , and I see Sparkxx has plenty of room for them (empty 25g?). I guess it depends on how often the relatives are visited...if once a week, no problem...if once a year, not such a good idea.
yeah I have to agree with angel aswell lol I visit them 3-4 times a week, so I guess no problem? could I just do water changes then instead of having to do all this DIY. I have to choose my subjects for school and stuff and, its kinda stressful xD I know work is ten times worse but having to revise to get into credit classes (highest class) is a nightmare! and changing the water and decholinating it doesn't take that long

what about chili/micro rasboras?
I'll have check these guys out, never seen them in my LFS lol
also, sorry you guys who have to read this and think "poor things goin in there" but I can keep it tidy
