I did like Seren, but I think getting Convicts was a mistake given the sizes of tanks I can realistically buy and maintain so I'm just waiting for the last 4 to be big enough to rehome

The one in with the goldfish displays against the front glass a lot, which her dad and seren did, but she also "flicks" sometimes like she's having a small seizure (could be the water as I've got problems).

Nature has prevailed again and the new kids are already having a go at the Danios, so I will be moving the Danios back in with the Goldfish for a while at least

On the plus side, two have formed a very close bond They're double the size of the other one that is in there with them - it's not lack of food, so I can only presume that she is a runt or they have a hormonal increase by being the dominant pair.
