Otto cats?

[evil Nick]

I am bringing this rainbow shark back and was thinking of getting a couple Otto's in place to help with algea since I hear their bio load is small. Would like 3 Otto's be a fair swap in capacity?

Being a sort of schooling fish 5-6 is recommended. especially with the rainbow shark. Rainbows can be territorial. I have schools of 5 in a community tank and my rainbow shark leaves them alone.

My shark is an *** and harasses everything. The LFS guy told us only get one shark cause they would kill each other if more than one was in the tank.
Im actually rehoming this shark before it kills my electric blue ram so I was thinking of getting some ottos

Even though Rams are less aggressive than most cichlids, they are still cichlids and he might feel threatened by them. That could be what it is or maybe I just got the shark that's really chill. Mine never bothers the other fish in the tank he keeps to himself.

If he continues to be an *** to all your fish maybe trade him for a new one? That's awesome he's active because mine hides a lot but just throwing some options out there. Following to see how it goes

What size is the tank and do you have a good amount of algae?

 

[ImACoolguy]

Mine is a 45 gallon by the way.

They definitely need to be in an established tank with a good amount of algae. Mine also like to graze on the plants.

He mainly focuses on my blue ram which was pricey. It's a 29 established with good algae

A 29g is too small for a Rainbow Shark.

Otos eat soft green algae. Control lighting if you are having algae issues.

For my first tank (I was 9) I had a rainbow in a 20g. Would shred the fins off of my tiger barbs and even killed a few. And yes, I thought he was an a ***. But my brother then had a rainbow in his 50 and it had been a model citizen. Conclusion: aggressive fish in small tanks=bad idea

Either way, still one of my all time favorite fish (and that's including saltwater)

Larger bin, an air stone, and heater until the morning or whenever you can get to the lfs

Okay to actually answer your question, in my opinion 3 Otos would be fine. I have two in my 29 and they absolutely thrive. They are extremely healthy. Otos are a great algae eater especially if you need something small and peaceful.

I have 5 otos in my 29 gallon as of yesterday. Didn't have time to get a head count in today but they should all be there. They seem to play sometimes when eating and is kinda funny to watch. Happy i got the number i did.
