As you probably know my Oto's are spawning regularly & I now have around 30 fry of various ages plus 8 adults. The tank they're in also houses a number of corys & rasboras so I'm going to be overstocked very soon. I'm thinking of setting up another 30 gallon & moving the corys & rasboras over & leaving the Oto's where they are as they're a nightmare to catch. I'm just wondering if anyone has ever done an Oto only tank or would it be too boring without a dither fish of some sort? thoughts please.
