Hi, I bought too snow king plecos (liposarcus anisitsi) when i started my tank. I had no idea how big these guys were gonna get!. Mine are only about 2 1/2 to 3 inches now, but ive only had them for about a month, and they were about 1 1/2 when i got them. I cant get a bigger tank becuz im invested in a saltwater one right now. My tank is only 29g, and i have 6 other fish with the plecos, what should i do??
