Lids and sucker fish discussion
Lets have a lids and sucker fish discussion. Some people might think goldies are going to leap out of their tanks so they keep the tank lids on. I imagine a fish would only do so as a last resort if it had the strength and had to get away from poor water quality. In some cases a fish might accidentally jump out during a spawning session, but this can be avoided if the water table is lowered. The space from the surface and the top of the tank should match the length of your longest fish in body length

What about goldies in a community tank with other fish ? Do they play well with others or EAT them ? Goldies are lil piggies.
Then there are sucker fish who keep the glass clean but do tend to get a taste for goldie slime when no one is looking injuring the goldie.
