I have a pristella tetras with a shortened gill plate. Is it hazardous to my other fish? It is currently in a 10 gallon tank alone And it has been for 8 months, but I’ve been wanting to add it to my tetra tank. I just need to know if it’s safe to be with other fish without the gill plate present. I posted a couple of pretty bad photos because it was hard to get him to show the gill, but I will post more when I get some.
