my title says it all i got a 7” yoyo loach at my store a week ago currently he is the only loach in my tank and tries to shoal with my pleco oscar and geophagus and id like to add some more yoyo loaches. the rest of the yoyo loaches are 2.5-3” and my oscar is probably 41/2” i know hell grow faster and if he tries to eat the loach itd get lodged in his mouth. so what is the smallest loach i could safely get? i could also get a bigger clown but the yoyo wouldnt benefit as much. the oscar has also left alone a 1” green terror so far. theres also a pile of rocks so the yoyo loaches have plenty of hiding spots.
