Lucky for you, Silverfang, your new one is definitely a she. I can see that little bend in the ventrals that only females have. Plus, she's got breeder's stripes. o.O
Olympia, you are so making me want to empty get rid of the congos and get a goldy for the 29. 3 dojos, 1 goldy, 1 filter rated for 50gals and 1 sponge filter. Doable? But I'd also have to get rid of the 3 remaining guppies and find a place to put the 2 remaining swordtail fry. I'd put them in the 20 but the last time I put fry that small in, the flagfish ate them.
